>Can anyone explain current caveats and/or limitations with current licensing?

You can pretty much ignore the FUD posts about Java licensing. There are long winded replies to why it is FUD, but the short answer is it is trivially not a problem. It only applies if you use the Oracle JDK and want a certain type of support. Most of the world doesn't, instead using one of the other free JDKs.

Java is *not* popular in the reddit, HN, etc memesphere. In the real world it remains incredibly popular and a huge number of organisations continue to pick it as their language of choice for back-end development.
