Description
Several tests on linux crash like this: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007fd96584fd7c, pid=11126, tid=140571679655696 # # JRE version: 7.0-b147 # Java VM: Java HotSpot(TM) 64-Bit Server VM (22.0-b02-internal-201109060011.never.7051798-fastdebug compiled mode linux-amd64 compressed oops) # Problematic frame: # V [libjvm.so+0x7ced7c] JNIHandleBlock::release_block(JNIHandleBlock*, Thread*)+0x3c # # Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again # # If you would like to submit a bug report, please visit: # http://bugreport.sun.com/bugreport/crash.jsp The problem is misalignment of the stack when calling throw WrongMethodTypeException. The other uses of generate_throw_exception always call it with an aligned stack but method handles don't enforce alignment while shifting arguments around.
