Are you using any helper libraries to handle these JDO queries? If so, what
happens if you use the low level Java datastore API to process cursor
queries?

Anyway - as you noted in your post - "*ExQ*" is a notice that there are no
more entities to return. It means functionally the same thing as a null or
empty cursor response. Presumably your code is already checking for a null
or empty query string; you can check for this value as well.
