Only if it could help other people...
I faced the same issue with 4.0.1. After looking at this thread, I did not see any cglib in soapui/lib. When I was about to give up, I checked the size of hermes-1.14.jar and the hermes 1.14 distribution jar file (hermes.jar) and found it was different. So I removed hermes-1.14.jar and link this file to the original distribution and voila!
Now it works perfectly.
Any SmartBear guy can confirm if the hermes-1.14.jar in the soapui distribution is the final release, or any RC?
Regards.
