Support roadmap for the Microsoft Build of OpenJDK

This article describes the support policy and roadmap for the Microsoft Build of OpenJDK binaries.

OpenJDK is the open source reference implementation of the Java SE Platform (Language and Virtual Machine), with its upstream project governed by Oracle Corporation at openjdk.java.net and with source code available at github.com/openjdk. The project is released under the GNU General Public License version 2 with Classpath Exception (GPLv2+CE). Java and OpenJDK are trademarks of Oracle Corporation.

The Microsoft Build of OpenJDK refers to a binary, or binaries, of the OpenJDK project that are compiled, packaged, and tested by Microsoft. Long-Term Support (LTS) releases of the Microsoft Build of OpenJDK are also tested against the Oracle’s Java Technology Compatibility Kit (TCK).

Support policy

This support policy applies to Long-Term Support (LTS) releases of the Microsoft Build of OpenJDK. The LTS releases of Microsoft Build of OpenJDK will receive free quarterly updates, available through microsoft.com/openjdk.

Microsoft Build of OpenJDK binaries may contain fixes and enhancements or backported fixes and backported enhancements that we deem important to our customers and our internal users but that have not been (and may not be) incorporated in the upstream OpenJDK project due to decisions outside of Microsoft’s control. Fixes and enhancements that have not yet been formally upstreamed will be clearly signposted in our release notes with source code available.

Azure Customer Support

Azure customer support is available for Azure, Azure Stack services, and Azure Arc customers with active Azure Support Plans. If you have an issue with the Microsoft Build of OpenJDK within an Azure environment, please submit a support request.
