is_thread_lock_aversive calls is_Java_thread on the current thread, which is the thread being destroyed by ~Thread below. In this context, because is_Java_thread is virtual with a definition in Thread that returns false, the result will be false, even though the thread used to be a JavaThread; because ~JavaThread has run it's no longer of that type.
