1. so i love .Net ecosystem and have been using ASP.NET since webforms 3.5. But in no way do I believe microsoft will be supporting dot net core stuff 5+ years down the line. I know its opensource but ms is the only major player that is actively developing it right now and after the Oracle/Android debacle I don't think other big players want to try it.

2/3) I think the communities are way too small.

So if you are in the Linux world and want to work on Back end . Then Java is your only options. You can mix in groovy/kotlin/scala to make dev less painful .Look at dropwizard and play framework the are an improvement on JSF/JSP/Spring mess.

I think the Oracle/Android debacle is why people should move from the Java ecosystem. Oracle has demonstrated that they'll countermand the spirit of the Java ecosystem and license any way they can if they think it's valuable enough.

It's a tax on success they want to impose. They want to turn Java into the same business model as their databases.
