> On WF-13 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.
