Well if you want to know where it happens:
Drop in replacment for Node, with no real runtime cost additionally, as the asserts must be actvated, and are removed at class loading time if not enabled. (The subrenderer was a bitch to fix, because I got the exact same error, but it was a internal jme state problem, not a threading one apparently.) However noticing that it was actually not my error took quite some time, wich is why this class was created.
