Knut Anders Hatlen commented on DERBY-418:
------------------------------------------
Derbyall ran cleanly. However, when running the repro for DERBY-1142 (without
rs.close()), I noticed that markUnused() was often called twice for the same
activation. This happens because both EmbedPreparedStatement and EmbedResultSet
call markUnused() in their finalizers. I think it would be a good idea to wrap
the body of markUnused() with "if (isInUse()) { ... }" to avoid false calls to
lcc.notifyUnusedActivation().

> I'm running a set of ~50000 queries on one table, using inserts and updates,
> and i want to be able to roll them back so i turned off autocommit using
> setAutoCommit(false). As the update runs, the memory used by the JVM
> increases continually until i get the following exception about 20% of the
> way through:
> ERROR 40XT0: An internal error was identified by RawStore module.
