Workaround for participate the PB-api in JTA transaction by implementing the Synchronization interface.
This may will be deprecated when we implemented a full JCA compliant connector.
When a new PersistenceBroker instance is created in method wrapBrokerWithPoolingHandle(org.apache.ojb.broker.PersistenceBrokerInternal, org.apache.commons.pool.KeyedObjectPool) the given PB instance is wrapped with PersistenceBrokerFactorySyncImpl.PersistenceBrokerSyncImpl before it was put to the PB-pool. When a PB instance was requested class try to lookup the current JTA transaction in wrapRequestedBrokerInstance(org.apache.ojb.broker.PersistenceBrokerInternal) before the pooled PB instance was wrapped with the PB handle. If a running tx was found the PB instance was registered with the transaction using the Synchronization interface.
