Microsoft has signed the Oracle Contributor Agreement, which gives it the right to participate in the development of OpenJDK.
According to a Microsoft employee, the company and its subsidiaries use Java in their products, so they decided to actively participate in Java development:
Microsoft and its subsidiaries are heavily dependent on Java in many aspects, and also offers Java runtimes in its Microsoft Azure cloud to its customers.
Let us remind you that earlier the Microsoft Azure division bought the company jClarity (https://blogs.microsoft.com/blog/2019/08/19/microsoft-acquires-jclarity-to-he…), one of the main contributors to the AdoptOpenJDK project and an active participant in the Java Community.
