Knut Anders Hatlen commented on DERBY-418:
------------------------------------------
Two more comments, and I'll stop complaining. :)
1. No need for a try/catch when the catch block only rethrows the exception:
try {
....
} catch (StandardException e) {
throw e;
}
2. In the Derby code, tabs are four characters wide. Apparently, your editor
displays tabs as eight characters, so the indentation doesn't match the
surrounding code when viewed in an editor which shows tabs as four characters.
Please update your tab settings and reindent the changes.
Thanks.

> 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.
