A DESCRIPTION OF THE PROBLEM :
We are experiencing an issue where one of our unit tests appears to hang during class loading.

For the hang on the linux machine, two threads are waiting for a class loader lock and the lock does not seem to be held by any other thread.

For the hang on the windows machine, one thread is still holding the class loader lock even though it is not class loading anything while two other threads are in fact doing class loading and are trying to get the class loading lock.

This issue seems to be related to:
