Donatas Ciuksys commented on DERBY-3303:
----------------------------------------

Sorry, I have migrated to DB2 already (have changed jdbc driver, connection 
url, and so on), so I don't have development environment suitable for Derby any 
more. And I don't know, how to build version 10.3.2.2. I have attached db 
scripts, it shouldn't be difficult to run them and check whether this issue 
still holds.

Good luck.
