(October 30, 2019) Today Microsoft sent an email to the primary mailing list of the OpenJDK project making an announcement many thought would never happen. That Microsoft is ready to contribute work to the OpenJDK project. Those of us with long enough memory recall the turmoil in the software industry because of Microsoft's predatory approach to Java nearly twenty years ago. In recent years Microsoft has had a huge change of policy, and is now readily working with all kinds of open source projects. That Microsoft is willing to join the OpenJDK project is a grand step forward, and is incredibly welcomed.
