Well, I got that error yesterday as well a days ago.

FYI, I updated the easy mock class extension from 2.2.1 to 2.2.2 a couple days

And I can't get the Concurrent Modification Exception for a while :)

Yep, I agree, but that would be pretty deterministic and reproducible.
I really didn't look into the code, so I don't know. Just thought
I'd put it out there and see who ever created the test would notice
something
probably bad with it concurrently speaking ;-)

Hi Polar,
I have not been able to reproduce this error on my windows box even on
repeated runs. Further this unit test itself doesn't have multiple
threads(unless easymock does something in its runtime) to get a
ConcurrentModification ex.
Just FYI: you don't need threads to get a
ConcurrentModificationException with the collections. Something simple
like:
List<String> lst = new ArrayList<String>();
lst.add("1");
Iterator<String> it = lst.iterator();
lst.add("2");
String s = it.next();
will result in the ConcurrentModificationException.

Let me see if changing the unit test in any way based on the EasyMock
code helps.

I get the following error intermittently, probably based on
system load.
It's a concurrent modification error on some List. Looks like
it has to do with Easymock, some misconception about lists, I think.
But in anycase, we should probably avoid this.
