Any ideas?

Hi Peter,
Thanks for the info.

What version of Geronimo are you using?

I've seen a similar LinkageError when attempting to run Geronimo
under the YourKit Java Profiler. Not sure, if this is related or not.
I hadn't really investigated the YourKit issue since it wasn't a
functional issue and was easy enough to have YourKit analyze
heapdumps, instead...

Do you have an app that illustrates the problem?

Hi,
Geronimo 2.0.2
I had the same problem with Glassfish.

This package doesn't include all classes, but you can use this ear to
reproduce the problem.

ear-1.0-SNAPSHOT.ear

Hi Peter,
I got most of the dependencies put together, but can't deploy the app. Currently because com.icesoft classes are missing.

Can you give us the full stacktrace?
