> Allow OpaqueFrameException for vthreads when suspended in a loop (not at an > event). This became necessary after > [JDK-8386116](https://bugs.openjdk.org/browse/JDK-8386116). The > ThreadReference.stop() spec allows for this: > > `This method may be used to send an asynchronous exception to a virtual > thread when it is suspended at an event. An implementation may support > sending an asynchronous exception to a suspended virtual thread in other > cases.` > > and > > `OpaqueFrameException - if the thread is a suspended virtual thread and the > implementation was unable to throw an asynchronous exception from the > thread's current frame` > > I also field [JDK-8390483](https://bugs.openjdk.org/browse/JDK-8390483) to > investigate if JVMTI should remove all vthread support for StopThread when > not at an event rather than having work just some of the time. > > The failure used to happen about 1 out of 50 runs. Tested with both platform > threads and with virtual threads about 200 times each with no issues. > > --------- > - [x] I confirm that I make this contribution in accordance with the [OpenJDK > Interim AI Policy](https://openjdk.org/legal/ai).
