Oracle provides this Oracle Java SE Support Roadmap, to help you understand maintenance and support options and related timelines. If you are looking for the latest free JDK release from Oracle under an open source license, please see jdk.java.net, or a free under commercial license see oracle.com/javadownload.
In this roadmap:
Oracle Customers are those Oracle customers with an active (1) Java SE Subscription and/or Java SE Desktop Subscription, (2) support contract for Oracle Java SE Advanced, Oracle Java SE Advanced Desktop, Oracle Java SE Suite, and/or Java SE Support, or (3) Java SE support entitlement for use of Java SE solely with another Oracle product (Visit My.Oracle.Support Note 1557737.1 - Support Entitlement for Java SE When Used As Part of Another Oracle Product – Requires Support Login).
Personal, Development and other Users are those who use Java SE under one of the permitted uses at no cost under the Oracle Technology Network License Agreement for Java SE. This includes individuals who use Java SE for free on personal desktops or laptops, or those who use Java SE for development use. Please see the Oracle Java SE Licensing FAQ for more information.
All Users are those who use Java SE 17 and later at no cost under the terms of the Oracle No-Fee Terms and Conditions License.
Oracle JDK and OpenJDK builds from Oracle
Since September 2017, Oracle provides JDK releases under a free open source license (similar to that of Linux). Availability and community support of OpenJDK releases provided by Oracle is listed separately on jdk.java.net.
Since September 2021, Oracle provides the Oracle JDK for Java 17 and later under a free use license for All Users. Oracle JDK releases for Java 16 and earlier versions continue to be made available under the Oracle Technology Network License Agreement for Java SE, which is free for Personal, Development and other Users only.
For more information on Oracle Java licensing, please see the Oracle Java SE Licensing FAQ.
Dates listed below apply only to the commercially supported Oracle JDK releases available to Oracle Customers.
Oracle Java SE Product Releases
Oracle provides Customers with Oracle Premier Support on Oracle Java SE products as described in the Oracle Lifetime Support Policy. For product releases after Java SE 8, Oracle will designate only certain releases as Long-Term-Support (LTS) releases. Java SE 7, 8, 11 and 17 are LTS releases. Oracle intends to make future LTS releases every two years meaning the next planned LTS release is Java 21 in September 2023. For the purposes of Oracle Premier Support, non-LTS releases are considered a cumulative set of implementation enhancements of the most recent LTS release. Once a new feature release is made available, any previous non-LTS release will be considered superseded. For example, Java SE 9 was a non-LTS release and immediately superseded by Java SE 10 (also non-LTS), Java SE 10 in turn is immediately superseded by Java SE 11. Java SE 11 however is an LTS release, and therefore Oracle Customers will receive Oracle Premier Support and periodic update releases, even though Java SE 12 was released.
Examples of some key product dates for Oracle Java SE product offerings include:
End of Public Updates of Java SE 8
Java SE 8 has gone through the End of Public Updates process for legacy releases. Oracle will continue to provide free public updates and auto updates of Java SE 8 indefinitely for Personal, Development and other Users via java.com. Oracle will provide at least 18 months notice on this page and other communication channels if an end of availability date is set. Developers can find Oracle Java SE updates, including Oracle Java SE 8, 11, 17 and current releases, on OTN. As of the April 16, 2019 quarterly critical patch update, Oracle Customers should access updates to Java SE 8 for commercial use from Oracle through My Oracle Support and via auto update where applicable (Visit My.Oracle Support Note 1439822.1 - All Java SE Downloads on MOS – Requires Support Login).
Oracle does not plan to migrate desktops from Java SE 8 to later versions via the auto update feature. This includes the Java Plugin and Java Web Start. Instead of relying on a browser-accessible system JRE, we encourage application developers to use the packaging options introduced with Java SE 9 to repackage and deliver their Java applications as stand-alone applications that include their own custom runtimes.
Web Deployment Technology and JavaFX
The Web Deployment Technology bundled with the Oracle JRE, consisting of the Java Plugin and Java Web Start has a shorter support lifecycle: only five years of Premier Support. The deployment stack was marked as deprecated and flagged for removal in Java SE 9 and Java SE 10. Oracle Java SE 11 and later versions do not include the Deployment Stack. As Java SE 8 will be the sunset release for the Deployment Stack Oracle extended support of Java Web Start on Java SE 8 until the end of Java SE 8 Extended Support. The Java Plugin (Java Applets) remains updated in Java 8, but may be removed at any time in a future release. Oracle Customers can find more information at My.Oracle.Support Note 251148.1 - Java SE 8 End of Java Plugin Support (requires login).
Java SE 8 is the recommended and only supported version of the deployment stack. The Java SE 8 deployment stack may be used to run Java SE 7, or Java SE 8 applications on Windows platforms. The Java deployment technology will not be supported beyond Java SE 8. See the Oracle Lifetime Support Policy for details.
JavaFX has been open sourced and redesigned to be available as a stand-alone library rather than being included with the JDK. Starting with Java SE 11, JavaFX is not included in the Oracle JDK. Support for JavaFX on Java SE 8 will continue until March 2025.
* Oracle Java SE product dates are provided as examples to illustrate the support policies. Customers should refer to the Oracle Lifetime Support Policy for the most up-to-date information. Timelines may differ for Oracle Products with a Java SE dependency (My.Oracle.Support Note 1557737.1 - Support Entitlement for Java SE When Used As Part of Another Oracle Product – Requires Support Login).
** These support timelines apply to Java client and server deployments of Java with the exception of Web Deployment Technology and JavaFX. For more information on those features, see below.
*** LTS/non-LTS designation and dates are subject to change.
**** Or later.
***** The Extended Support uplift fee will be waived for the period June 2019 - July 2022 for Java SE 7. The Extended Support uplift fee will be waived for the period March 2022 - December 2030 for Java SE 8. During this period, you will receive Extended Support as described in the Oracle Technical Support Level sections of the Technical Support Policies.
† Excluding Deployment Technology and JavaFX, which is described in a separate section.
