getallstktr001 is not virtual-thread-safe. JVMTI GetAllStackTraces() only returns platform thread stacks, not virtual threads. Additionally, 40 threads all block on native RawMonitorEnter() which pins carrier threads and causes deadlock when run as virtual threads (confirmed during JDK-8382273 testing). Reverted TestThread to extends Thread.
