             Summary: TransactionSynchronizer registered as interposed synchronization leads to ordering issue when using hibernate
                 Key: JBJCA-1357
                 URL: https://issues.jboss.org/browse/JBJCA-1357
             Project: IronJacamar
          Issue Type: Bug
    Affects Versions: 1.4.5
            Reporter: Alexanderke Pinske


The TransactionSynchronizer (to cleanup connections) is registered as an interposed synchronization. Hibernate also registers its synchronization (to close the underlying JDBC connection handle) as interposed.

This leads to undefined ordering, which in my case runs the JCA Synch before the Hibernate Synch. This leads to a log of IJ000316 and the connection being killed.

I think that platform specific cleanup should be executed after all application level synchronization have run, therefore it should be registered with the TM (not the TSR).

http://www.ironjacamar.org/doc/roadto12/txtracking.html describes this as an application misbehaviour. But I don't think the application has any means of controlling the ordering in this scenario.

If I do not provide a TSR to the TransactionIntegrationImpl (which would lead to the registration of the TransactionSynchronizer via TransactionManager - thus non-interposed) has the problem that AbstractPool uses the TSR to check if a transaction is actually in progress.

I don't know if my rationale is correct. Could you please comment on the issue?

Thanks!
