    public class JdbcAggregationRepository
extends org.apache.camel.support.service.ServiceSupport
implements org.apache.camel.spi.RecoverableAggregationRepository, org.apache.camel.spi.OptimisticLockingAggregationRepository
    JDBC based AggregationRepository JdbcAggregationRepository will only preserve any Serializable compatible data types. If a data type is not such a type its dropped and a WARN is logged. And it only persists the Message body and the Message headers. The Exchange properties are not persisted.
