[Hibernate] NPE in cirrus.hibernate.collections.Map

[Mark W. <mor...@SM...>]

Gavin,

You've been busy!  Unfortunately, CVS is is not compilable at the 
moment.  Lots of errors about ambiguous references due to multiple 
classes with the same name.

I'm also getting an NPE in cirrus.hibernate.collections.Map @ line 180 
when the collection is empty.  A patch to fix this is attached.
