Have you noticed, by any chance, a ConcurrentModificationException somewhere in your tests?
I noticed that the ExcaliburComponentManager doesn't correctly synchronize on its m_componentHandlers hashmap, and that might be the root of our problems...
A ConcurrentModificationException happens when you invoke a "put" or "remove" operation on the HashMap at the same time you are using an Iterator. The Iterator will throw the ConcurrentModificationException because the information that the iterator is going through is no longer valid.
I don't recall there being anything in the ECM dispose method that would
cause this to happen. There are a couple things I would check though:
* Request scoped lookups * The BucketMap in Commons Collections
I would double check ECM as well--I just have to get another release done at work before noon. After that, I will see what I can dig up.
I just posted a patch to BugZilla which fixes the ConcurrentModificationException I am observing. Per each page I look up few bazillion components (roughly a couple of hundred AFAICS) in few bazillion different sitemaps (four).
