LibGDX has a plan however - move to Intel Multi-OS Engine
(although LibGDX was able to finagle a free license for small developers).
And I wish I could say I'm surprised that Oracle's not jumping in to buy this tech, as it seems like it would be a terrific addition to the Java toolset. But adding innovation to Java is, to say the least, not Oracle's strong suit.
Good luck with whatever you end up doing next though, seriously, whether it's libgdx-related or not. Y'all are good people, you do good stuff.
In any case, thanks! I've read your book (Beginning Android Games) and used libgdx (though nothing finished or published) and enjoyed both!
