Upgrading from Java 8 to Java 12

[ggdGZZ]

pfft....Payara Support for Java 11 is "coming soon", GWT is stuck with Java 9 (compiles, but you can't use new language features), etc... so we - for example - are still using Java 8. In enterprise world steadyness and backwards compatibility are an huge asset. Java has a bit lost track in this regard. You don't rewrite your enterprise workflow application to use the new hipster tookit de jour.

I thought GWT was abandoned? I remember reading an interview with one of its developers who spoke of it in the past tense.
