This appears to be a problem that occurs when one build is done right after 
another. 

MVn clean clears it up (temporarily).  The problem appears to be related to the 
code generation for collections. Previously collections would never be built 
twice on the same directory. 

As I get time I will be messing with this to get it cleaned up. In the meantime 
we have a work around and I can even disable the building of the collections.  

Thoughts?

Benson?  Are you out there?
