             Summary: Improve clustering thread pool validation
                 Key: WFLY-5693
                 URL: https://issues.jboss.org/browse/WFLY-5693
             Project: WildFly
          Issue Type: Feature Request
          Components: Clustering
    Affects Versions: 10.0.0.CR4
            Reporter: Radoslav Husar
            Assignee: Radoslav Husar
            Priority: Optional


Currently, configuration where e.g. max threads is smaller than min threads is accepted in the model, is not validated by jgroups either and then fails at runtime
