> Current implementation of JDWP agent performs full cleanup in VMDeath callback. It includes stopping agent threads and waiting for they to finish. If for whatever reason agent threads are not finished, VM will hang in VMDeath callback, regardless the fact that agent threads are daemon threads and should not cause VM hang. 
> In VMDeath callback agent should just close debug session and return form callback without full cleanup. Agent threads will complete cleanup actions and finish. Even if they are not finished for whatever reason, this will not prevent VM from exit.
