Subject: DERBY-412 (Connection.toString() formatting) patch uploaded
FYI, I attached another patch for DERBY-412, based on Tomohito's
comments. Tomohito, would you be willing to review the changes?
I don't think I can commit yet (I'm a little unclear on my current
status), so perhaps you could also commit it if it looks good, Tomohito?
Thanks,
David
