After installing GWT 2.2.0 I keep getting the following error when
trying to start my app in Dev Mode:

Is SmartGWT compatible with GWT 2.2? See http://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/3171958b76f90ddb

thanx for the link, good point!

But, alas, it doesn't apply for my case. I don't get any error as
listed and my app actually works with both versions.

The error in my OP appears only every now and then. I start my app in
Dev Mode and get the error, I restart it, say 3 or 4 times, with the
same error, and then, on the next restart it all of a sudden works
just fine.
Until now, I have not been able to figure out under which
circumstances/conditions it either works or doesn't.

Being a ConcurrentModificationException it points to a timing problem,
which could be caused by tons of things...

Hello,

Is this the whole stacktrace?
Are you sure it's not your code who modifies some map while iterating
over it?

yes, this is the whole stack trace.
yes, I'm sure I'm not modifing some map while iterating.
