> (more detail on the log files)[2]
> The error does not show as long as the "OF DATA" isn't specified. It also
> won't show if the whole FOR UPDATE clause is omitted.
> I would also like some comments and advice on how to proceed on converting
> holdCursorJDBC30.sql as it is affected by this problem. The original test
> does an update on a cursor with the "FOR UPDATE OF DATA" clause, and this
> isn't working on the Java version of the test. Do I go around it by removing
> the FOR UPDATE clause or should I wait for this bug to get fixed?
