Microsoft is a huge contributor to OpenJDK, with more than 50 patches for OpenJDK, covering areas such as garbage collection fixes, MacOS packaging, build and infrastructure.

Microsoft Build of OpenJDK binaries may come with backported fixes and enhancements deemed important to users. Though some of the fixes may not have been formally backported upstream and signposted in OpenJDK release notes.

Open competition with Oracle in the Java distribution space



The move has been seen by analysts as a serious competition for Oracle in the Java space, as Java is one of the most popular programming languages today, used for almost everything from enterprise applications to robots.

Microsoft is increasingly experiencing growth in its customer use of Java across the company’s cloud services and development tools, haven deployed more than 500,000 JVMs internally, excluding Azure services and customer workloads. Indeed, Microsoft Build of OpenJDK would set up the company to compete with Oracle in the Java space.
