We found it during gtests on a JDK 17 alpine build, since in this version the JavaTestThread class overwrote the post:_run() method without deregistering the stack at the VirtualMemoryManager. JDK-8215948 fixed this, so I would not expect any tests to be affected.

Outside of test the code is only executed if a thread calls AttachCurrentThread() and exits without calling DetachCurrentThread.().
