Could this be a bug in the Cooja simuator or the JVM?

Hard to say. It's not an Cooja-Problem, because the JVM should make sure things don't break, but throw an exception. Lately I also had some problems with the JIT. You can give java -Xint a try. Might es well be a bug in Contiki(!). Unfortunately I'm not familiar enough with JNI to say how well stuff is sandboxed.
