Line 12 above is likely calling this class:

http://grepcode.com/file/repo1.maven.org/maven2/org.apache.wicket/wicket-core/1.5-RC7/org/apache/wicket/application/DefaultClassResolver.java?av=h#DefaultClassResolver

That class returns the TCCL from the getClassLoader().

So looks like the TCCL does not have visibility to the MSC module, so CNFE for the ServiceName class. I wouldn't expect a webapp TCCL to have visibility, although you'd need to ask the EE guys on the dev list or IRC to confirm it's not supposed to.

What's the solution? Make Wicket an AS module and give it visibility?
Or specific AbstractClassResolver impl for AS 7?

[1] describes how to add module dependencies to a webapp. I don't know enough about Wicket to know why it would be needing to deserialize the ServiceName class. Doesn't sound like a good behavior. [1] https://docs.jboss.org/author/display/AS71/Class+Loading+in+AS7

I will take a look what is it trying to deserialize. But I guess it's a reference leak, should be filled/nullified prior to de/serialization.
