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

The full version string for this update release is 11.0.22+9 (where “+” means “build”). The version number is 11.0.22. Full release notes for Java 11 can be found here.

If you need to run Java applications, it is enough to download and install the JRE (Java Runtime Environment). If you’re developing Java applications, you’ll want to download the JDK, which also includes the JRE.

• (i) For personal use on a desktop or laptop computer, such as playing games or running other personal applications.
• (ii) For development, testing, prototyping and demonstration of applications, including for use of/with profiles, debuggers and integrated development environment tools.
• (iii) For use with certain Qualified Products, such as Oracle SQL Developer, or as an end user of a software application created by a Qualified Product. (referred to as “Schedule A” and “Schedule B” products in the OTN License Agreement for Java SE)

The latest version of Java is Java 22 or JDK 22 released in March 2024. However, many versions of Java are actively maintained for compatibility purposes. Java 8, Java 11 and Java 17 are the three long-term support versions recommended by Oracle. You can download the version

Java 8 is the last free public software update for commercial use, which explains why it remains popular. Oracle plans to maintain it until at least 2030. You should also know that some programs may refer to Java 8 as version 1.8.0.

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 that anyone can download it for personal or development use at no cost. Oracle charges for long-term support, but this is optional.

IANA Data 2020a

JDK 11.0.22 contains IANA time zone data 2021a. For more information, see Time zone data versions in the JRE software.

Security basis

The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 11.0.22 are specified in the following table:

JRE Family Version = JRE Security Baseline (full version string)

• 11 = 11.0.22+9
• 8 = 8u371-b11

Keeping the JDK up to date

Oracle recommends that the JDK be updated with each critical update. To determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.

Critical patch updates, which contain security issues, are announced one year in advance on Critical Patch Updates, Security Alerts, and Bulletins. It is not recommended that this JDK (version 11.0.13) be used after the next critical patch update scheduled for January 18, 2022.

What is new

JDK 11.0.22 contains IANA time zone data 2022g which contains the following changes:

• The northern edge of Chihuahua changes to US time.
• Large parts of Greenland will stop changing clocks after March 2023.
• Fix some pre-1996 timestamps in Northern Canada.
• C89 is now obsolete; please use C99 or later.
• Portability fixes for AIX, libintl, MS-Windows, musl, z/OS.
• In C code, use more C23 functions if available.
• C23 hourgm is now supported by default.
• Dishes for improbable integer overflows.

Previous release notes

Oracle recommends that the JDK be updated with each critical update. To determine if a release is the latest, the Security Baseline page can be used to determine which is the latest version for each release family.

Critical patch updates, which contain security issues, are announced one year in advance on Critical Patch Updates, Security Alerts, and Bulletins. It is not recommended that this JDK (version 11.0.16) be used after the next critical patch update scheduled for October 18, 2022.

New functions

core-libs/java.net

â HTTPS channel binding support for Java GSS/Kerberos

Added support for TLS channel binding tokens for Negotiate/Kerberos authentication over HTTPS through javax.net.HttpsURLConnection.

Channel binding tokens are increasingly needed as an enhanced form of security that can mitigate certain types of socially engineered, 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 certificate) and higher-level authentication credentials (such as username and password). The server can then detect if the client has been tricked by a MITM and shut down the session/connection.

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

Other notes

â JDK Bundle Extensions truncated when downloading with Firefox 102

On oracle.com and java.com, certain JDK package extensions are truncated on download when using Firefox version 102. The downloaded packages have no file extension such as “.exe”, “.rpm”, “.deb”. If you cannot upgrade to Firefox ESR 102.0.1 or Firefox 103 when it is released, as a workaround you can:

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

Changes

core-libs/java.io

â Enable alternate data streams in Windows 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 just immediately after a single drive letter. It also allows paths representing NTFS Alternate Data Streams (ADS), such as “filename:streamname”. This restores the default behavior of java.io.File to what it was before the April 2022 CPU, where strict validity checks were not performed by default on file paths on Windows. To re-enable strict path checking in java.io.File, the jdk.io.File.enableADS system property should be set to false (casebook is ignored). This may be preferable, for example, if Windows special device paths such as NUL: are not used.

Error corrections

This release is based on the previous CPU and contains no 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
