SUMMARY: We have established that during VM termination when `exit()` has been invoked, we can still execute code that tries to use Semaphore's for which the static destructor has already been executed, resulting in the observed assertion failures. Separate issues are created for the numerous (directly or indirectly) statically defined Semaphore instances, so that their safe usage can be evaluated and corrected if needed. The Semaphore is unsafe if it can be accessed by a `NonJavaThread`, or by a `JavaThread` in a safepoint-safe state.
