             Summary: 8.2.0.Final build hangs
                 Key: WFLY-4113
                 URL: https://issues.jboss.org/browse/WFLY-4113
             Project: WildFly
          Issue Type: Feature Request
          Components: Test Suite
    Affects Versions: 8.2.0.Final
            Reporter: Peter Major


When trying to build 8.2.0.Final locally, my build just hangs indefinitely while executing a unit test in the controller module:

{noformat}
Running org.jboss.as.controller.ModelControllerClientTestCase
{noformat}

Running jstack against the build suggests that there is a deadlock between

Preferably locks should be obtained in the same order across the different code paths to prevent deadlocks.
