Rick Hillegas updated DERBY-4869:
---------------------------------

    Attachment: derby-4869-21-ab-implicitlyClosedResultSets.diff

Thanks for the encouragement, Dag. Attaching derby-4869-21-ab-implicitlyClosedResultSets.diff.
This is a second rev of the patch for handling closeOnCompletion() when ResultSets close implicitly.
I am running regression tests now.

In this version of the patch, the Statement-closing logic is moved inside ResultSet.markClosed().
I found that I could make this work by factoring Statement.markClosed() into 2 pieces:

1) A piece which closes the ResultSets.

2) A piece which closes all of the other Statement resources.

Now the closeOnCompletion logic calls only the second piece of the Statement.markClosed()
logic. This ought to be safe since the ResultSets have already been closed.

I have added Dag's test case to the regression test for this behavior.


Touches the same files as the previous version of the patch.
