Problem with jocl - EXCEPTION_ACCESS_VIOLATION

Hello,
I was making a program using Java with OpenCL. However, I cannot run the program.

I encountered EXCEPTION_ACCESS_VIOLATION crash. With some debugging, I found that it was occured in CLContext.create(), more specifically, in native call CLAbstractImpl.dispatch_clGetExtensionFunctionAddressStatic() while performing free(), when retriving "_addressof_clCreateEventFromGLsyncKHR" in CLProcAddressTable.(the previous ones were loaded successfully.)

I don't think it is the problem of my program, because the demo programs crashed too with same log. As I assume, this would be my system's problem. If so, how can I check it?

Crash Log from my program : http://pastebin.com/NQ5mEpUZ
Crash Log from demos(typically same) : http://pastebin.com/Qbia7YDA

PS. Where can I found the source code of native library?
