----------------------------------------

             Summary: Intermittent module loading failure in InterdependentDeploymentTestCase
                 Key: WFCORE-2235
                 URL: https://issues.jboss.org/browse/WFCORE-2235
             Project: WildFly Core
          Issue Type: Bug
          Components: Modules, Server
    Affects Versions: 3.0.0.Alpha22
            Reporter: Brian Stansberry


InterdependentDeploymentTestCase tests deployment handling of a set of interdependent deployments, where some of the dependencies are optional.

The test intermittently fails due to a ModuleLoadException while deploying one of the modules:

The most notable bit of info in the log is:

The interrelated-c.jar deployment depends (*not optionally*) on interrelated-a.jar.The failure occurs during execution of a management op that redeploys interrelated-a.jar. FWIW, another deployment in the set, interrelated-f.jar, does depend optionally on interrelated-c.jar.

The full stdout output for the failed test in the above linked CI run also includes a dump of all MSC services following the failure. Note though that the failure does not result in MSC not obtaining stability. Inability to reach stability was the initial problem that led to the introduction of this test (see https://github.com/wildfly/wildfly-core/pull/2099.)
