Fixed In Version:
Doc Type: Bug Fix
Doc Text:
In JBoss EAP 6, transaction recovery operates by asking resources for their view of in-doubt transaction branches using "RecoveryHelpers" provided by other subsystems. When a deployment registers one of these helpers, a lock is taken. The same lock is acquired when recovering a resource. If the resource is slow to complete a recovery request, then the subsystem deployment (which is waiting for the lock) is similarly delayed. In this release the contention on the lock is broken and subsystems deploy as expected.

Description James Livingston 2014-08-24 22:32:36 UTC
Recovery scans can delay subsystem deployments because of contention on the lock XARecoveryModule._xaResourceRecoveryHelpers. If recovery takes a long time, for example caused by Database performance or connectivity issues, it can stall JBoss startup.
