> Currently kill001 assumes that JVMTI StopThread (via JDI > ThreadReference.stop) is not supported for virtual threads. > [JDK-8306034](https://bugs.openjdk.org/browse/JDK-8306034) is adding support > for StopThread on a virtual thread as long as it is suspended and mounted. > This means, for example, it will work for virtual threads in the following > conditions: > - Debuggee in a loop and suspended > - Debuggee at a breakpoint and suspended > > But will continue to not work in the following situations: > - Debuggee in a loop but not suspended > - Debuggee suspended but unmounted, such as during a call the Thread.sleep() > > kill001 suspends all threads at a breakpoint and then does a "jdb kill" on > each thread, which translate to `ThreadReference.stop()`, so this is expected > to work now. > > Most of the changes involve undoing the virtual thread specific code that was > added to the test as part of > [JDK-8282385](https://bugs.openjdk.org/browse/JDK-8282385).
