A B updated DERBY-3279:
-----------------------
Attachment: d3279_10_3_merge.patch
I ran the following "svn merge" commands to port this change back to 10.3:
svn merge -r 616125:616126 https://svn.apache.org/repos/asf/db/derby/code/trunk
svn merge -r 617547:617548 https://svn.apache.org/repos/asf/db/derby/code/trunk
The second command saw a conflict due to svn # 614745, which went into trunk
but not into 10.3. So I had to do a manual resolution of the conflict--which
simply amounted to adjusting for 2 lines in junit/JDBC.java.
I'm attaching d3279_10_3_merge.patch, which encapsulates the "svn merge"
commands plus the conflict resolution. I ran the 10.3 "derbyall" and
"suites.All" regression tests and saw no failures.
I'll wait a day or two to see if Ajay's testing illuminates any other problems;
if not, then I'll go ahead and commit the merge patch to the 10.3 branch.

> Running the following produces the error seen in Derby 10.3.X but not in
> 10.2.X nor in 10.1.X.
> Don't know if this related to DERBY-3231.
