Concurrent access to HashMap in RsIterator

I've got an app using OJB. It works fine on Windows (all my descriptors are OK and datasource config too) but when I deploy on AIX I've got this error :

org.apache.ojb.broker.PersistenceBrokerException: java.util.NoSuchElementException: Could not obtain next object: concurrent access to HashMap attempted by Thread[http8080-Processor2,5,main]

Does someone knows  the source of this problem ?
