[jira] Commented: (DERBY-1706) NullPointerException occurs when
trying to create a table in schema SESSION
[ http://issues.apache.org/jira/browse/DERBY-1706?page=comments#action_12434833 ]
Yip Ng commented on DERBY-1706:
-------------------------------
Thanks for the additonal background information, Mamta. I have tried the second patch DERBY1706NPEwithSessionSchemaV2diff.txt and the NPE no longer exists.
Perhaps a comment is useful here for explaining why sdCatalog's UUID can be null in certain cases.
if (sdCatalog != null && sdCatalog.getUUID() != null)
...
Otherwise, the patch looks good to me. +1
