The crash in free() is the only one that tells me anything at all, and my only guesses are 1) mixed allocator usage or 2) application error, e.g. double free().  I really don't know anything about how the JVM is structured internally , how it interacts with malloc, how it uses/abuses dlopen(), etc., so I'm not going to be of much help without a lot more background information.

Thanks,
Jason
