However, with the exception of some communication missteps around the licensing changes (which actually ended up in fully open source JDK, as opposed to the mostly open source JDK in Sun's time), Java has actually done great under Oracle.

Amazing what having resources can do for a project, eh?

I mean, I'm not thrilled with the licensing model around GraalVM (since it's another "mostly" open source situation), but business is business, I guess. I'd personally prefer that they treat it the same as Java proper, and fund it via support contracts/subscriptions.
