After accessin Runtime page in console, the following error message can be found in server log. ERROR [org.jboss.as.controller.client] (XNIO-1 task-7) JBAS014781: Step handler org.jboss.as.domain.controller.operations.coordination.DomainFinalResultHandler@671b9b7f for operation composite at address [] failed handling operation rollback -- nul
I cannot reproduce this. Based on Darran's comment above I am setting this to MODIFIED so QE can verify against the ER4 build.
Verified 6.2.0.ER4
I can now recreate this readily in WildFly, as can anyone: https://issues.jboss.org/browse/WFLY-2273. It doesn't happen in EAP; I'm not sure why. But the immediate issue in WFLY is an NPE, and the same kind of NPE could happen in EAP, so I'm going to backport the fix.
Verified with 6.2.0.CR1
