When running the runtime/ParallelClassLoading/bootstrap/random/dynamic-init/anonymous-complex SQE test, it fails to properly synchronize on all threads.

In particular in this case, the log indicates thread #35 seems to finish before the main thread starts waiting for completion of all threads (i.e. 50 in this case).

This leads to the main thread waiting for a thread that does not exist any more, leading to timeout.
