What is Java?

Java is a programming language and software platform. Examples of applications that use Java are numerous and widespread but include web browsers, office applications and even mainstream games like Minecraft are based on Java.

What is Java JDK?

The Java Development Kit (JDK) is the full-featured software development kit for Java developers. It has everything the JRE has, but adds the compiler (javac) and tools (like javadoc and jdb). The JDK allows you to create and compile Java programs.

Is Java free to use?

Yes, Java is free to use under the jdk.java.net license. This means anyone can download it for personal or development use at no cost. Oracle does charge for long term support, but this is optional.

IANA Data 2020a

JDK 11.0.16 contains IANA time zone data 2021a. For more information, refer to Timezone Data Versions in the JRE Software.

Security Baselines

The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 11.0.16 are specified in the following table:

JRE Family Version = JRE Security Baseline (Full Version String)

New Features

core-libs/java.net

➜ HTTPS Channel Binding Support for Java GSS/Kerberos

Support has been added for TLS channel binding tokens for Negotiate/Kerberos authentication over HTTPS through javax.net.HttpsURLConnection.

Channel binding tokens are increasingly required as an enhanced form of security which can mitigate certain kinds of socially engineered, man in the middle (MITM) attacks. They work by communicating from a client to a server the client’s understanding of the binding between connection security (as represented by a TLS server cert) and higher level authentication credentials (such as a username and password). The server can then detect if the client has been fooled by a MITM and shutdown the session/connection.

The feature is controlled through a new system property jdk.https.negotiate.cbt which is described fully on the Networking Properties page.

Other Notes

➜ JDK Bundle Extensions Truncated When Downloading Using Firefox 102

On oracle.com and java.com, certain JDK bundle extensions are getting truncated on download when using Firefox version 102. The downloaded bundles have no file extension like «.exe», «.rpm», «.deb». If you are not able to upgrade to Firefox ESR 102.0.1 or Firefox 103 when it is released, then as a workaround you can:

• manually add a file extension to the file name after download.
• use a different browser

Changes

core-libs/java.io

➜ Enable Windows Alternate Data Streams by default

The Windows implementation of java.io.File has been changed so that strict validity checks are not performed by default on file paths. This includes allowing colons (‘:’) in the path other than only immediately after a single drive letter. It also allows paths that represent NTFS Alternate Data Streams (ADS), such as «filename:streamname». This restores the default behavior of java.io.File to what it was prior to the April 2022 CPU in which strict validity checks were not performed by default on file paths on Windows. To re-enable strict path checking in java.io.File, the system property jdk.io.File.enableADS should be set to false (case ignored). This might be preferable, for example, if Windows special device paths such as NUL: are not used.

Bug Fixes

This release is based on the previous CPU and does not contain any additional security fixes. The following issues have also been resolved:

• JDK-8284920 Category: xml Subcategory: javax.xml.path Summary: Incorrect Token type causes XPath expression to return incorrect results
• JDK-8284548 Category:xml Subcategory: jaxpInvalid Summary: XPath expression causes StringIndexOutOfBoundsException

Java SE 11.0.15 Advanced — Bundled Patch Release (BPR) — Bug Fixes and Updates

The following sections summarize changes made in all Java SE 11.0.15 BPR releases. The BPR releases are listed below in date order, most current BPR first. Note that bug fixes in previous BPRs are also included in the current BPR.

• JDK-8221741 Category: client-libs Subcategory: 2d Description: ClassCastException can happen when fontconfig.properties is used
• JDK-8212904 Category: client-libs Subcategory: javax.swing Description: JTextArea line wrapping incorrect when using UI scale
• JDK-8282583 Category: xml Subcategory: jaxp Description: Update BCEL md to include the copyright notice

➜ Support cross-realm MSSFU

The support for the Kerberos MSSFU extensions [1] is now extended to cross-realm environments.

By leveraging the Kerberos cross-realm referrals enhancement introduced in the context of JDK-8215032, the ‘S4U2Self’ and ‘S4U2Proxy’ extensions may be used to impersonate user and service principals located on different realms.

security-libs/java.security

➜ Customizing PKCS12 keystore Generation

New system and security properties have been added to enable users to customize the generation of PKCS #12 keystores. This includes algorithms and parameters for key protection, certificate protection, and MacData. The detailed explanation and possible values for these properties can be found in the «PKCS12 KeyStore properties» section of the java.security file.

Also, support for the following SHA-2 based HmacPBE algorithms has been added to the SunJCE provider: HmacPBESHA224, HmacPBESHA256, HmacPBESHA384, HmacPBESHA512, HmacPBESHA512/224, HmacPBESHA512/256

Removed Features and Options

security-libs/java.security

➜ Removed Root Certificates with 1024-bit Keys

The following root certificates with weak 1024-bit RSA public keys have been removed from the cacerts keystore:

+ alias name «thawtepremiumserverca [jdk]» Distinguished Name: EMAILADDRESS=premium-server@thawte.com, CN=Thawte Premium Server CA, OU=Certification Services Division, O=Thawte Consulting cc, L=Cape Town, ST=Western Cape, C=ZA + alias name «verisignclass2g2ca [jdk]» Distinguished Name: OU=VeriSign Trust Network, OU=»(c) 1998 VeriSign, Inc. — For authorized use only», OU=Class 2 Public Primary Certification Authority — G2, O=»VeriSign, Inc.», C=US + alias name «verisignclass3ca [jdk]» Distinguished Name: OU=Class 3 Public Primary Certification Authority, O=»VeriSign, Inc.», C=US + alias name «verisignclass3g2ca [jdk]» Distinguished Name: OU=VeriSign Trust Network, OU=»(c) 1998 VeriSign, Inc. — For authorized use only», OU=Class 3 Public Primary Certification Authority — G2, O=»VeriSign, Inc.», C=US + alias name «verisigntsaca [jdk]» Distinguished Name: CN=Thawte Timestamping CA, OU=Thawte Certification, O=Thawte, L=Durbanville, ST=Western Cape, C=ZA

Previous release notes

security-libs/java.security

➜ -groupname Option Added to keytool Key Pair Generation

A new -groupname option has been added to keytool -genkeypair so that a user can specify a named group when generating a key pair. For example, keytool -genkeypair -keyalg EC -groupname secp384r1 will generate an EC key pair by using the secp384r1 curve. Because there might be multiple curves with the same size, using the -groupname option is preferred over the -keysize option.

security-libs/javax.net.ssl

➜ Support for certificate_authorities Extension

The «certificate_authorities» extension is an optional extension introduced in TLS 1.3. It is used to indicate the certificate authorities (CAs) that an endpoint supports and should be used by the receiving endpoint to guide certificate selection.

With this JDK release, the «certificate_authorities» extension is supported for TLS 1.3 in both the client and the server sides. This extension is always present for client certificate selection, while it is optional for server certificate selection.

Applications can enable this extension for server certificate selection by setting the jdk.tls.client.enableCAExtension system property to true. The default value of the property is false.

Note that if the client trusts more CAs than the size limit of the extension (less than 2^16 bytes), the extension is not enabled. Also, some server implementations do not allow handshake messages to exceed 2^14 bytes. Consequently, there may be interoperability issues when jdk.tls.client.enableCAExtension is set to true and the client trusts more CAs than the server implementation limit.

core-libs/java.lang

➜ POSIX_SPAWN Option on Linux

As an additional way to launch processes on Linux, the jdk.lang.Process.launchMechanism property can be set to POSIX_SPAWN. This option has been available for a long time on other *nix platforms. The default launch mechanism (VFORK) on Linux is unchanged, so this additional option does not affect existing installations.

POSIX_SPAWN mitigates rare pathological cases when spawning child processes, but it has not yet been excessively tested. Prudence is advised when using POSIX_SPAWN in productive installations.

security-libs/javax.net.ssl

➜ Support for X25519 and X448 in TLS

The named elliptic curve groups x25519 and x448 are now available for JSSE key agreement in TLS versions 1.0 to 1.3, with x25519 being the most preferred of the default enabled named groups. The default ordered list is now:

x25519, secp256r1, secp384r1, secp521r1, x448, ffdhe2048, ffdhe3072, ffdhe4096, ffdhe6144, ffdhe8192

The default list can be overridden by using the system property jdk.tls.namedGroups.

security-libs/java.security

➜ jarsigner Preserves POSIX File Permission and symlink Attributes

When signing a file that contains POSIX file permission or symlink attributes, jarsigner now preserves these attributes in the newly signed file but warns that these attributes are unsigned and not protected by the signature. The same warning is printed during the jarsigner -verify operation for such files.

Note that the jar tool does not read/write these attributes. This change is more visible to tools like unzip where these attributes are preserved.

client-libs/2d

➜ Oracle JDK11u for Solaris Now Requires harfbuzz to be Installed

Oracle JDK-11.0.10 and later for Solaris 11 requires that the OS provide the package library/desktop/harfbuzz as part of the system installation. This package is provided for Solaris 11.3 and later.

$ pkg info harfbuzz Name: library/desktop/harfbuzz Summary: HarfBuzz is an OpenType text shaping engine Description: HarfBuzz is a library for text shaping, which converts unicode text to glyph indices and positions. HarfBuzz is used directly by libraries such as Pango, and the layout engines in firefox. Category: Desktop (GNOME)/Libraries State: Installed Publisher: solaris

This is a desktop library, but the font processing it does is part of some common backend server workloads. It should always be considered as required.

If this library is missing, then the pkg mechanism will require it during installation of the JDK. If installing the JDK by using a tar.gz bundle (for example) and the library/desktop/harfbuzz package is missing, a runtime link failure will occur when this package is needed.

JDK-8251907 (not public)

core-libs/java.time

➜ JDK time-zone data upgraded to tzdata2020d

The JDK update incorporates tzdata2020d. The main change is

Palestine ends DST earlier than predicted, on 2020-10-24.

Please refer to https://mm.icann.org/pipermail/tz-announce/2020-October/000062.html for more information.

core-libs/java.time

➜ JDK time-zone data upgraded to tzdata2020c

The JDK update incorporates tzdata2020c. The main change is

Fiji starts DST later than usual, on 2020-12-20.

Please refer to https://mm.icann.org/pipermail/tz-announce/2020-October/000060.html for more information.

core-libs/java.time

➜ US/Pacific-New Zone Name Removed as Part of tzdata2020b

Following the JDK’s update to tzdata2020b, the long-obsolete files named pacificnew and systemv have been removed. As a result, the «US/Pacific-New» Zone name declared in the pacificnew data file is no longer available for use.

Information regarding this update can be viewed at https://mm.icann.org/pipermail/tz-announce/2020-October/000059.html.

Bug Fixes

• This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update. For a more complete list of the bug fixes included in this release, see the JDK 11.0.10 Bug Fixes page.

security-libs/java.security

➜ Weak Named Curves in TLS, CertPath, and Signed JAR Disabled by Default

• Weak named curves are disabled by default by adding them to the following disabledAlgorithms security properties: jdk.tls.disabledAlgorithms, jdk.certpath.disabledAlgorithms, and jdk.jar.disabledAlgorithms. The named curves are listed below.
• With 47 weak named curves to be disabled, adding individual named curves to each disabledAlgorithms property would be overwhelming. To relieve this, a new security property, jdk.disabled.namedCurves, is implemented that can list the named curves common to all of the disabledAlgorithms properties. To use the new property in the disabledAlgorithms properties, precede the full property name with the keyword include. Users can still add individual named curves to disabledAlgorithms properties separate from this new property. No other properties can be included in the disabledAlgorithms properties.
• To restore the named curves, remove the include jdk.disabled.namedCurves either from specific or from all disabledAlgorithms security properties. To restore one or more curves, remove the specific named curve(s) from the jdk.disabled.namedCurves property.
• Curves that are disabled through jdk.disabled.namedCurves include the following: secp112r1, secp112r2, secp128r1, secp128r2, secp160k1, secp160r1, secp160r2, secp192k1, secp192r1, secp224k1, secp224r1, secp256k1, sect113r1, sect113r2, sect131r1, sect131r2, sect163k1, sect163r1, sect163r2, sect193r1, sect193r2, sect233k1, sect233r1, sect239k1, sect283k1, sect283r1, sect409k1, sect409r1, sect571k1, sect571r1, X9.62 c2tnb191v1, X9.62 c2tnb191v2, X9.62 c2tnb191v3, X9.62 c2tnb239v1, X9.62 c2tnb239v2, X9.62 c2tnb239v3, X9.62 c2tnb359v1, X9.62 c2tnb431r1, X9.62 prime192v2, X9.62 prime192v3, X9.62 prime239v1, X9.62 prime239v2, X9.62 prime239v3, brainpoolP256r1, brainpoolP320r1, brainpoolP384r1, brainpoolP512r1
• Curves that remain enabled are: secp256r1, secp384r1, secp521r1, X25519, X448. See JDK-8233228

security-libs/org.ietf.jgss:krb5

➜ Support for Kerberos Cross-Realm Referrals (RFC 6806)

• The Kerberos client has been enhanced with the support of principal name canonicalization and cross-realm referrals, as defined by the RFC 6806 protocol extension.
• As a result of this new feature, the Kerberos client can take advantage of more dynamic environment configurations and does not necessarily need to know (in advance) how to reach the realm of a target principal (user or service).
• Support is enabled by default and 5 is the maximum number of referral hops allowed. To turn it off, set the sun.security.krb5.disableReferrals security or system property to false. To configure a custom maximum number of referral hops, set the sun.security.krb5.maxReferrals security or system property to any positive value.

Java Development Kit 64-bit (also known as JDK) contains the software and tools that you need to compile, debug, and run applets and applications that you’ve written using the Java programming language. JDK has as its primary components a collection of programming tools, including javac, jar, and the archiver, which packages related class libraries into a single JAR file. This tool also helps manage JAR files, javadoc — the documentation generator, which automatically generates documentation from source code comments, jdb — the debugger, jps — the process status tool, which displays process information for current Java processes, javap — the class file disassembler, and so many other components.

The JDK 64-bit also comes with a complete Java Runtime Environment, usually called a private runtime. It consists of a Java Virtual Machine and all of the class libraries present in the production environment, as well as additional libraries only useful to developers, and such as the internationalization libraries and the IDL libraries.

Oracle seems to be moving towards a rapid release model as we can see the Java 9 was released after Java 8 and after some time, Java 10 was released. Now Java 11 has been released. The good thing about the rapid release model is that the users will enjoy more features being added to Java more often. The downside of this approach is that the users, as well as the developers, have to keep up to date with every new release of Java version.

Java 11 is a lighter version as the support for Java EE, CORBA modules, Java FX and NASRON javascript engine has been ended. Moreover, it introduces a new HTTP client API which supports HTTP 1.1 and HTTP 2. It will offer features of Java along with some further enhancements and changes. The changes made are incremental with small feature changes and updates to the earlier version.

Explaining the release cycle of Java versions

Java 11 is the first version to be released as Long Term Release Support. This means that Java 11 will be supported for the next 8 years and users will keep on getting new fixes and updates of Java 11.

Although Oracle has moved to a rapid release model it will also continue the LTRS model. A new Java version will be released after every three years and each Long Term Release Support version will be supported for a total of eight years. This means that Java 17 will be the next LTRS version which will be released somewhere in 2021.

New Features

Let’s quickly go through some of the new features added to Java 11 and then we’ll give links to Java 11 offline installers.

Epsilon garbage collector

It is known as a no-op garbage collector. The main functionality of this garbage collector is to handle memory allocation. It does not collect any garbage. It is used to check the performance of GC algorithms. It is useful for short-lived tasks.

Flight Recorder

Before that, it was a commercial feature but is available open-source now. It records the Operating system and JVM event to a file

Nest-Based Access Control

It provides the support of nested classes through inner classes while removing the need for compilers to insert accessibility-broadening bridge methods.

Local-Variable Syntax for Lambda Parameters

This feature was introduced in java 10 but it has been enhanced in the current version. The parameters for implicitly typed variables can be declared using the variables

Unicode 10

The support for Unicode 10 has been added which includes bitcoin sign too.

Single File Source-Code Programs

This allows java source code directly executed by the java interpreter but the limitation with that feature is that all classes should be included in one file

Low-Overhead Heap Profiling

The heap allocations can be traced in a low overhead framework.

Transport Layer Security (TLS) 1.3

Transport Layer Security (TLS)  version 1.3 has been implemented in Java 11. However, no performance enhancement has been made for datagram transport layer security.

 ZGC: Garbage Collector

It is a scale-able low-latency garbage collector used for applications that require multi-Gigabyte heap collection.

Changes

The following changes have been made

• Nashorn JavaScript Engine, Java EE and CORBA modules are deprecated
• JAXB is removed from the JDK in JDK 11
• JavaFX libraries have been removed from core and are available as a separate download.
• Auto-update previously available on Windows and macOS for JRE installations is no longer available.
• Language Support for French, German, Italian, Korean, Portuguese (Brazilian), Spanish, and Swedish translations are no longer there.
• Java Mission Control has been separated from JDK.
• Updating packaging format for Windows and macOS has been changed. For Windows, it is now from tar.gz to .zip and for macOS is from .app to.dmg
• In OpenJDK  JRE or Server JRE is not offered only JDK is available. In order to create a smaller custom runtime, a link can be used.

These changes have been made to make the version lighter but while migrating some issues and errors will be encountered by the users as the earlier version provides support for them. Although such initiative has been taken from Java 9 these features had not bee completely deprecated

To download the latest offline installers of Java 11 JRE and JDK, please follow the steps below:

1. Go to this Oracle download link
2. Accept the agreement
3. Click on the link in front of the platform you want to download.

The following downloads are available:

• Java 11 JDK for Windows 64-bit
• Java 11 JDK for Linux RPM 64-bit
• Java 11 JDK for Linux TAR 64-bit
• Java 11 JDK for MacOS DMG 64-bit

Conclusion

If we have to summarize the features of Java 11, it introduces HTTP/2 support and brings in features like Nest-based access controls, a no-op garbage collector, TLS 1.3, enhanced Keystore mechanisms. These features may be enough to entice you to upgrade to Java 11. What are your thoughts about this version of Java?
