             Summary: ManagedExecutorService: Wrong RequestCount on Exception 
                 Key: WFLY-13177
                 URL: https://issues.redhat.com/browse/WFLY-13177
             Project: WildFly
          Issue Type: Bug
          Components: EE, Server
    Affects Versions: 16.0.0.Final, 10.1.0.Final
            Reporter: Guido Jäkel
            Assignee: Brian Stansberry


On WF-10 and WF-16 we observe a serious bug of the RequestCount of the RequestController while using ManagedExecutorService.submit() or ...execute() in the edge case of a full queue. In this case, the caller gets a RejectedExecutionException, but in the RequestController, the number of active requests is erroneously incremented.

This will lead to a false and monotonously increasing number of active requests. And in case of a limitation configured by the maxRequestCount feature, which is best practice for production environments, over the time this will lead to deadlock of the RequestController and herewith the complete activity of the Wildfly at all.
