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 games like Minecraft are based on Java.

The full version string for this update release is 11.0.19+9 (where "+" means "build"). The version number is 11.0.19. Complete release notes for Java 11 can be found here.

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

For full information and terms, refer to the OTN License Agreement for Java SE. The OTN License Agreement for Java SE for current Oracle Java SE releases allows them to be used, without cost:

  • (i) For personal use on a desktop or laptop computer, such as to play games or run other personal applications.
  • (ii) For development, testing, prototyping, and demonstrating applications, including to use by/with profilers, debuggers, and Integrated Development Environment tools.
  • (iii) For use with some approved products, such as Oracle SQL Developer, or as an end user of a software application created by an approved product. (referred to as "Schedule A" and "Schedule B" Products in the OTN License Agreement for Java SE)
  • (iv) With identified Oracle Cloud Infrastructure products.

The latest version of Java is Java 20 or JDK 20 released on March, 2023. 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 you need below:

Java 8 is the last free software public update for commercial use, which explains why it remains popular. Oracle plans to maintain it until at least 2030. Also, you should know that some applications might 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 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 11.0.19 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 11.0.19 are specified in the following table:

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

  • 11 = 11.0.19+9
  • 8 = 8u371-b11

Keeping the JDK up to Date

Oracle recommends that the JDK is updated with each Critical Patch Update. In order 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 vulnerability fixes, 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's New

  • Much of Greenland stops changing clocks after March 2023.
  • Fix some pre-1996 timestamps in northern Canada.
  • C89 is now deprecated; please use C99 or later.
  • Portability fixes for AIX, libintl, MS-Windows, musl, z/OS.
  • In C code, use more C23 features if available.
  • C23 timegm now supported by default.
  • Fixes for unlikely integer overflows.

Previous release notes

Oracle recommends that the JDK is updated with each Critical Patch Update. In order 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 vulnerability fixes, 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 Features

core-libs/java.net

â 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

â 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

â 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
