--------------------------------------

             Summary: Misbehaving XAResources may delay deployments
                 Key: JBTM-2242
                 URL: https://issues.jboss.org/browse/JBTM-2242
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Application Server Integration
    Affects Versions: 5.0.2, 4.17.22
            Reporter: Michael Musgrove
            Assignee: Michael Musgrove
             Fix For: 4.17.23, 5.0.3


Recovery scans can delay subsystem deployments because of contention on the lock XARecoveryModule#_xaResourceRecoveryHelpers:

 XARecoveryModule#resourceInitiatedRecoveryForRecoveryHelpers takes the lock and then makes calls to the resource which can potentially hang transiently. Meanwhile, deployments which register recovery helpers are delayed whilst waiting for the lock to be released (in XARecoveryModule#addXAResourceRecoveryHelper).
