i have this issue with JNA when after some number of calls, the system crashes with EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0327d1dc, pid=1956, tid=728

i was playing with my code, and essentially came to one loop with simply one JNA native call in it. it's windows XP to C dll. after some number of calls , could be 300 or 10000, it blows up. i prepare all the memory and structures outside the loop.

now i put System.gc() inside the loop, and BOOM! it blows up after the first call. what do i need to know about JNA and garbage collector? apparently it cleans up something that it being referenced by DLL. how do u find these things?

thanks argyn
