easiest java physics engine

what in you opinion is the easiest java 3d physics engine?

A good physics library I heard is good is JBullet, ported by our very own jezek2, found here.

OK. i’ve looked through the demos, and i kind of get it. what would be the best way to get a map into jbullet?btBvhTriangleMeshShape maybe?

Jinngine and dyn4j are nice too.
