Quite possibly, you are being affected by DERBY-47:

Since we believe that this problem has been fixed in Derby 10.3,
it would be wonderful if you could download the DERBY 10.3 beta
release from http://wiki.apache.org/db-derby/DerbyTenThreeRelease
and give it a try to see how it affects your query.



P.S. Myrna, I noticed that it was a bit hard to find a good
      hyperlink to the beta release. Perhaps you could put a
      link to the 10.3 beta on http://db.apache.org/derby/
      and/or http://db.apache.org/derby/derby_downloads.html
      as those would be natural places to look?  Or are we
      not supposed to do that because it's still a beta release?
