             Summary: HTTP + EJB - UnsupportedOperationException trying to write to an AbstractMap

            Reporter: Tomas Remes
            Assignee: Stuart Douglas
             Fix For: 13.0.0.Beta1


[~tremes] Has hit this failure when running some tests against our OpenShift images using WF code from, I believe, 12 CR1.

{code}
13:03:50,832 ERROR [org.jboss.as.ejb3.remote] (default task-1) WFLYEJB0150: Could not write method invocation failure for method public abstract void com.redhat.xpaas.ejb.server.RemoteCounter.increment() on bean named CounterBean for appname  modulename ROOT distinctname  due to: java.lang.UnsupportedOperationException

He or [~luck3y] can give you more details re the specific test.

Just walking through code, my guess is the Collections.emptyMap() produced at [1] is getting passed through the stack to the failing code. (I'm filing this because I did this bit of brilliant analysis. ;) )
