So here is something interesting!
I added some more debug statements to my code and found this:
| 15 Feb 2008 15:39:19,847: DEBUG com.myapp.persistence.QueryServiceImpl -

Put a bit more succinctly, the getCategories method actually works! I see the
categories themsleves listed as they should be in the log. But for some
reason, the getCategories method gets called again, and it is that second call
that generates the exception I described originally.
Any insight into why this might happen is greatly appreciated.
Thanks.
