JGroups reports a deadlock using virtual threads with async profiler.

A mixed mode thread dump shows a thread of interest waiting in JvmtiVTMSTransitionDisabler::VTMS_transition_disable_for_all, and the Attach Listener in same as it calls JVMTI SetEventNotificationMode in its Agent_OnAttach function.

It seems that a virtual thread posting an event while holding the interrupt lock.

Note that we don't have a reproducer yet.
