IllegalStateException in DelegatingPersistenceBroker.getBroker
While doing a OMDG query like this (after some other committed
transactions):
OQLQuery queryObj = _odmg.newOQLQuery();
String query = ... // some basic select
_tx.begin();
queryObj.create(query);
DList result = (DList)queryObj.execute();
_tx.commit();
I get an IllegalStateException thrown in
DelegatingPersistenceBroker.getBroker() while the query executes. When
debugging I can see that in the execute method the collection is correctly
retrieved but the following locking (performLockingIfRequired) seemingly
tries to use an already closed broker.
Any idea what might cause this ?
BTW, I use the CVS version from August 1st with MySQL.
Thanks,
Tom

Well, yes the tests pass (with hsqldb that is), sort of (see my other
mail from yesterday). But I'll check whether I can reproduce it in a test.

Hi Tom,
do all odmg junit tests pass?
Now OJB is more strict in handling PB instances.
If PB.close() was called on a given instance no further
method calls can be done. Your sample
code seems ok, thus it sounds like a bug.
regards,
Armin
