Microsoft bought jClarity last year with the stated intent of using its technology to optimize Java workloads on Azure. London-based jClarity promotes its commercial support for AdoptOpenJDK binaries as being "the drop-in replacement for Oracle's Java/JDK." Microsoft has been a sponsor of the AdoptOpenJDK project since 2018.
This new OpenJDK port is based on the OpenJDK tip branch (16+), according to Microsoft's post and can run most workloads, including SPEC SERT after Microsoft's contributions towards the new platform combination are accepted, as well as all of the SPEC Java suites.
"While optimizing Java for Azure remains one of our core goals, it is crucial to share that we are involved in other initiatives to make the Java platform even better on areas besides the Cloud," said Bruno Borges, Principal Program Manager of the Java Engineering Group, in today's blog post.
Microsoft also has more than 1,000 developers who are building native or Xamarin apps for Android, and these developers still need Java on their development environments and their continuous integration/continuous delivery pipelines.
