Alexanderke Pinske created JBJCA-1357: ----------------------------------------- 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! -- This message was sent by Atlassian JIRA (v7.5.0#75005)
