Hi, I did have a look at your most recent crashes, and I'm not sure where the problem is exactly. I cannot reproduce them on my machine.
Since the crashes are random, my guess is that the problem might come from the fact that you are running on a multi-core machine (as seen in the hs_err_pid log). The problem might be that the Java-C++ interface does not work correctly under concurrent garbage-collection. However, this is just a guess. We will definitely look into these crashes more carefully in the future, but I don't have any hope of finding the problem soon.
