@Edward Agreed JVM is awesome and it is a work of many smart people and this is obvious if one looks into the JDK code. But given Oracle history of business practices and other decisions it is a bit hard to convince oneself that everything is going to be OK and that they actually care about open source. Even the module system that they are trying to come up with is something that motivated by the problem they have faced internally.
To reiterate again just watch this video https://www.youtube.com/watch? v=9ei-rbULWoA My statements are not solely based on this video but I certainly would give good weight for James Gosling. I tend to think that Oracle has not closed Java because they know that cant get money from users because these days not many people are willing to pay even for distributed databases so I don't think anyone would pay for programming language. In short, Let me end by saying Oracle just has lot of self interest but I really hope that I am wrong since I am a big fan of JVM.
