> I encountered a memory leak case. The MAT info :
> !leak.jpg!
> Full error message is :
> {code:java}
> Cannot get Long result for param = 8 for column "`FUNCS`.`FUNC_ID`" :
> Operation not allowed after ResultSet closed{code}
> This is because there is a bug in the JDOPersistenceManager.retrieveAll code.
> {code:java}
> // code placeholder
> JDOPersistenceManager{
> public void retrieveAll(Collection pcs, boolean useFetchPlan) {
> this.assertIsOpen();
> ArrayList failures = new ArrayList();
> Iterator i = pcs.iterator();
> while(i.hasNext()) {
> try {
> this.jdoRetrieve(i.next(), useFetchPlan);
> } catch (RuntimeException var6) {
> failures.add(var6);
> }
> }
> if (!failures.isEmpty()) {
> throw new JDOUserException(Localiser.msg("010038"),
> (Exception[])((Exception[])failures.toArray(new Exception[failures.size()])));
> }
> }
> }
> {code}
> In some extreme cases the function of next() does not work . This will
> result in a very large failures ArrayList like as shown above.
>
