[ http://issues.apache.org/jira/browse/DERBY-147?page=comments#action_61494 ] Bernd Ruehlicke commented on DERBY-147: ---------------------------------------
I fixed it as Satheesh suggested. I have tested it in our location and it seams to work. I have not have time to 1) Write Tests 2) Figure out how to check it into the trunk I would like to work on this asap - it would help with just a few "dummy" steps how and from where to check out the file, check it back in. And where teh JUnit tests should be checked into.
