Description Missing name CLA 2011-04-15 08:59:45 EDT 
Build Identifier: 2.2.0

I was able to reproduce an exception with 5 classes.
Enhancing works fine, but on schema generation the attached exception occurs.

When I'm using my whole object model, the excpetion seems to be thrown twice and in that case, I don't get the text of the DescriptorException, just:
[java] Descriptor Exceptions: 
[java] ---------------------------------------------------------

So initially I had no clue where to start - that should be fixed, too.

I re-checked the spec, just to be sure.
The object model is valid (according to 2.5 + 2.6).
