I am running cvs head with a few minor patches (to LoopController,
LoopControlPanel and the resource files) on win2k using jdk1.4.0_01.
Sometimes JMeter encounters a ConcurrentModificationException thus:

My Thread Group is currently configured to have only 1 thread, but 2 loops.
I have three listeners in my Test Plan, View Results Tree, Graph Results and
Aggregate Report. I do have quite a large number of HTTP Requests in my jmx
file - it is currently 792KB.
I would hazard to guess that this is the exact same thing as in this message
from the archive:
http://archives.apache.org/eyebrowse/ReadMsg?[EMAIL PROTECTED]
ache.org&msgId=515387
Does anyone have an idea of what I might do to resolve this problem?
Thanks,
Scott
