Looks like a resource called 'mypackage.MyClass fi usuari -->  </div><div id'
was requested - that's the output after urldecoding the string from
your exception
message. I guess somewhere in your webapp resource url's are output incorrectly,
or someone actually entered that string as url in his browser. Maybe
you're trying
to output html comment inside html comments, where the 'inner' comments
terminate the 'outer' comments early, and leave an extra --> behind.
So, I guess you don't have a ClassLoader issue here, nor a Serialization issue.

cheers,
Jonas
