I'm a long time Java developer that's starting to learn on the NXT 2.0. Are there any limitations to using the Java API? Which language is the most robust on the platform?

I found [this post][lego-nxt-programming-tip] which mentions many of the alternatives. The answer is helpful, but doesn't mention the different languages' limitations.
