AIUI we are using the thread's context classloader to load XMLBeans - 
David has already raised that as a issue with the ConfigBuilder's and I 
think this might be the same problem. However, the plugin can't rely on 
the tool behaving properly so we should try and find a way that the 
plugin can get the mapping right on its own. Of course, having our tool 
behave right would help too :-)

I think that is too much of a restriction to impose.

Working around it in the way we use XMLBeans.
