On April 6, Microsoft is rolling out a preview of the Microsoft Build of OpenJDK, a long-term support distribution of the OpenJDK. It includes the binaries for Java 11 and is available on x64 server and desktop environments on Windows, as well as on MacOS and Linux. Microsoft also is publishing today a new early-access release for Java 16 on Windows on Arm. (Last June, Microsoft s Java Engineering Group announced it had completed the first phase of porting OpenJDK for Windows on Arm.)
Microsoft bought jClarity in 2019 with the stated intent of using its technology to optimize Java workloads on Azure. jClarity touted 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. The company s jClarity purchase kicked off the official formation of the Java Engineering Group in Microsoft s Developer Division, officials said.
