As one can see the issue is from libjvm.so JVM environment and not an application problem

No: the issue is most likely with libbCacheService.so, and not libjvm.so. I don't know what the origin of libbCacheService.so is, but given that google only finds this question when I search for it, I suspect that it's your application.

Besides, the same setup and code on Ubuntu works fine

That is quite often the case: an application exhibiting undefined behavior works "fine" on one system, and crashes on another.

Your first step should be building libbCacheService.so with debug info, enabling core dumps, and checking from the core that whatever libjvm.so function is invoked from JNIEnv_::GetObjectClass() is called with correct arguments.

P.S. It looks (from si_addr) that libjvm.so dereferenced a NULL pointer. Possibly because you passed a NULL pointer to it as one of the parameters.
