The domain test suite for RBAC is consistently failing on SPARC Solaris, as can be seen at https://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/eap-62-RBAC-QE-testsuite-Solaris-matrix/

Given that all the tests are running against the same domain, the first failure is the most significant and the others are just symptoms of inconsistent test environment.

The first failure looks like this:

Failed: {
    "address" => [
        ("core-service" => "management"),
        ("access" => "authorization"),
        ("role-mapping" => "MainGroupDeployer"),
        ("include" => "user-MainGroupDeployer")
    ],
    "operation" => "remove"
}
Result: {
    "outcome" => "failed",
    "result" => undefined,
    "failure-description" => "JBAS010839: Operation failed or was rolled back on all servers.",
    "rolled-back" => true,
    "server-groups" => {
        "server-group-a" => {"host" => {"master" => {"master-a" => {"response" => {
            "outcome" => "failed",
            "rolled-back" => true,
            "response-headers" => {"process-state" => "restart-required"}
        }}}}},
        "server-group-b" => {"host" => {"slave" => {"slave-b" => {"response" => {
            "outcome" => "failed",
            "failure-description" => "JBAS014807: Management resource '[
    (\"host\" => \"slave\"),
    (\"server\" => \"slave-b\"),
    (\"core-service\" => \"management\"),
    (\"access\" => \"authorization\"),
    (\"role-mapping\" => \"MainGroupDeployer\"),
    (\"include\" => \"user-MainGroupDeployer\")
]' not found",
            "rolled-back" => true,
            "result" => undefined
        }}}}}
    }
}

and it happens when tearing down the test environment, as can be seen from the stacktrace:

I'm assigning to myself, as this is most likely a test issue, though it might have something in common with https://issues.jboss.org/browse/WFLY-2270
