Something that many keep forgeting with their Oracle hate, is that Oracle has been part of the Java eco-system since the early days.

They did the NC Java station alongside Sun, were the first RDMS to support Java stored procedures, ported their installers and GUI tooling to Java, created their own JVM, later bought BEA, and created their own JEE implementation, among other Java frameworks.

Didn't they get rid of everything that didn't bring profit like JEE and NetBeans? The only part of Java that Oracle cares about is paid(supported)LTS versions, as there is no free LTS version anymore, with new quick release schedule. Well, that was the idea, some companies like Amazon ( https://aws.amazon.com/corretto/ ) want to backport fixes.

Java and its ecosystem is a cash cow. Any company will be happy to tend to a cash cow
