Please provide exact steps to reproduce.
NPE is a result of some parsing issue and data is required to identify 
it's reason.

I generated services for all entity classes and then removed all services and tried to generate service for single entity only (I'm using Jersey libraries)

Comment 7 Denis Anisimov 2012-09-07 10:31:33 UTC 
I'm able to reproduce the issue but it requires very specific source data:
I've deleted all generated services as David suggest.
Also I've deleted all entities except one.
In the result I had a compilation error because there is a reference to dropped 
entity.
Such reference introduces the unresolved closure for the entity and this is the 
reason of NPE.
I can't imagine the other cases where the unresolved entities are discovered.
