Hello, I am using OJB 1.0.4 and Spring 1.2.8. A spring interceptor is
handling transactions for me. All my OJB code is written using the
Spring PersistenceBrokerDaoSupport class.
I have a long running process that does quite a bit of data
manipulation. It is a single threaded app that starts up Spring, does
it's work, then ends. It runs from the command line.
All the database work happens in a single Spring managed transaction
against a single Oracle database.
If this process runs for a while, I will receive an exception in the
log like this:
2006-06-21 18:59:27,619 [Finalizer] ERROR
org.apache.ojb.broker.accesslayer.ReportQueryRsIterator :: Error when
try to remove RsIterator resource listener
java.lang.ArrayIndexOutOfBoundsException: 107
at
org.apache.ojb.broker.core.PersistenceBrokerAbstractImpl.removeListener(Unknown
Source)

at java.lang.ref.Finalizer.access$100(Finalizer.java:14)
at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:160)
This might happen many times during the process. The process doesn't
stop running after one of these exceptions. At the end of the run,
when Spring should commit the transaction, it does a rollback with
this message:
2006-06-21 19:09:19,786 [main] ERROR

It looks like the garbage collector is trying to collect an object
that is being used. Has anyone seen this before? Any ideas how it
can be fixed?
Thanks
Jay
