Anybody get this error?
It pops up “randomly” in a dialog and ends my application.
I get it alot, so much that now I have to fix it to go on 
So after examining the code I can see this is an assert on a lock for data access.
That sounded like a possible threading problem, so I made sure that my object accesses were all on the same thread (pain, stupid C code :-)), and the error seems to have stopped.
We need ODE in pure Java. Jeff find us some funding
