Daniel John Debrunner commented on DERBY-418:
---------------------------------------------

The change ignores the exception:

+                } catch(StandardException e) {
+                    StandardException.plainWrapException(e);
+                }

That code just creates an exception (in the call to plainWrapException)  and 
then throws it away.

> 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.
