Doc Text:
In JBoss EAP 6 the Transaction Manager recovery operateraton queries resources for their view of in-doubt transaction branches. A "RecoveryHelper" which JCA registers helps to achieve this. When the resource is removed from the system the helper is de-registered. Previous versions of the product contained a race condition in the code whereby if the removal happened during a "recovery scan" then the helper was not removed. This resulted in the possibility that transaction recovery would continue using resources even though they a deployment had removed it from the server. The race condition has been removed in this release of JBoss EAP 6.

Description Tom Ross 2014-09-18 10:04:41 UTC 
There is some code in XARecoveryModule#removeXAResourceRecoveryHelper that defers removal of recovery helpers if a scan is in progress but skips the removal otherwise.
