@yvsubhash and @rhtyd, now these changes seem to solve the problem. These synchronization and transaction manually managed are a real problem. We should plan to move to a real JPA implementation together with a framework like Spring-data. Then, these problems are solved by the framework.
@yvsubhash do you have these changes running in production already?
