[jira] Commented: (DERBY-1356) Positioned update/delete when
positioned after last or before first causes NullPointerException
Posted by "Dag H. Wanvik (JIRA)" <de...@db.apache.org>.
[ http://issues.apache.org/jira/browse/DERBY-1356?page=comments#action_12414540 ]
Dag H. Wanvik commented on DERBY-1356:
--------------------------------------
This is a simple patch which adds handling of the two exceptional
cases indicated in the title of this issue. I have verified that the
added test reveals the error before the fix code is added.
I recommend it for commit.
