Hi,
we have a problem concerning OJB 0.9.5. Our application is running in a
multiprocessor environment. During testing with several threads which are
create a lot of database traffic we get messages like this:

org.apache.ojb.broker.metadata.ClassNotPersistenceCapableException: Error
getting field:reiseRef in object:de.bayern.bfd_r.RKSImport.fassade.Reise
Running the application only with one thread we don't have any problems.
Do someone have an idea what the reason can be?
Regards,
Oliver Paulus
