[jbossts-issues] [JBoss JIRA] Commented: (JBTM-359) Transaction Bridging can timeout b ecause it bundles phase zero work into prepare

    [ https://jira.jboss.org/jira/browse/JBTM-359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12469142#action_12469142 ] 

Jonathan Halliday commented on JBTM-359:
----------------------------------------

Having the bridge manage a set of Synchronizations itself seems like duplication of effort, given that the JTA already has code for that. Better to change the subordinate tx API exposed by the JTA so that instead of being prepare (with implicit beforeCompletion) + commit/rollback (with implicit afterCompletion) it exposes before+after as distinct methods which the bridge can then call from its impl of the XTS VolatileParticipant methods. That means postponing this one until the API changes in the JTA (JBTM-560) are done.

> Bridged  (from XTS to JTA) transaction synchronizations currently get executed at prepare time which can cause very long delays. This may cause the transaction coordinator to timeout the prepare or cause another participant to timeout. It would be better if the JTA brdge manager intercepted add synch requests and registered its own phase zero synchronization to run them.
