Still investigating. Trying to isolate the problem
https://github.com/kinow/commons-collections/tree/COLLECTIONS-661-1
No luck so far. I have an environment where it happens over 90% of the time.
Tried debugging a few times, adding some sysout statements to see if there was
anything suspect... yesterday enabled findbugs in test to look for any issue in
the test classes. Nothing yet.
