I figured out how to reproduce the error.
With JRebel's Stripes plugin enabled test.jsp takes some 1 minute to load. While
waiting for it to load, I open another browser tab and do a bit of browsing
around. That would trigger the error about 50% of the time.
Sometime the error will be with test.jsp, sometime the error will occur at the
other page that I was browsing.
There is a bug in JRebel definitely. But I am not sure whether the JRebel bug is
causing the ConcurrentModificationException - or it is causing a bug in Stripes
to surface.
I am using the Eclipse Helios SR1. JRebel plugin was updated to the most recent
version.
Cheers,
Yee
Below is the stack trace (with test.jsp).
