[PB]many persistence broker instances

Hi,
When I call:

	inst = PersistenceBrokerFactory.createPersistenceBroker(new
PBKey("repository.xml"));
	// doing some selects,updates deletes here
	// the App creates 2 PBs
	
	inst.getCollectionByQuery(new QueryBySQL(clazz,"SELECT * FROM
mytable"));// the App creates 6 PBs here
	
	inst.close();


The application instanciates 6 persistence broker (allthough there where
allready two created before)

I use proxies for references and mytable has 14 references.

Is this a normal behavior?

When you've finished with the PB you should call PB.close();

Yes, PB provide many service methods, thus OJB graps instances from
the pool for intern use.
