             Summary: If a CMR resource is deployed concurrently then it will overwrite the list of resources that are expected to behave as CMR
                 Key: WFLY-13632
                 URL: https://issues.redhat.com/browse/WFLY-13632
             Project: WildFly
          Issue Type: Bug
            Reporter: Thomas Jenkinson
            Assignee: Brian Stansberry


Inspecting https://github.com/wildfly/wildfly/blob/master/transactions/src/main/java/org/jboss/as/txn/service/CMResourceService.java#L73 we can see that it will overwrite the map in https://github.com/jbosstm/narayana/blob/48818111d12d2e51b52082a00bcb606040c36546/ArjunaJTA/jta/classes/com/arjuna/ats/jta/common/JTAEnvironmentBean.java#L1111 because it first get's a copy of a map (https://github.com/wildfly/wildfly/blob/master/transactions/src/main/java/org/jboss/as/txn/service/CMResourceService.java#L63 -> https://github.com/jbosstm/narayana/blob/48818111d12d2e51b52082a00bcb606040c36546/ArjunaJTA/jta/classes/com/arjuna/ats/jta/common/JTAEnvironmentBean.java#L1089) so the maps won't be equal.

This will result in WildFly overwriting the list of resources that Narayana will treat as CMR.
