Quick question

[Tom Rodriguez]

Async exceptions can be delivered to a thread during a safepoint so  
yes you need to check for a pending exception.  Check out  
JavaThread::check_and_handle_async_exceptions and  
JavaThread::handle_special_runtime_exit_condition and  
generate_handler_blob in sharedRuntime_<arch>.cpp.  Generally speaking  
if you call into the runtime for any reason you should be checking for  
pending exceptions.
