Chao Wang commented on WFCORE-2656:
-----------------------------------

I have also seen this test fails today with error:
{noformat}
Failed tests: 
  DeploymentTestCase.testFilesystemScannerRegistration:253->addDeploymentScanner:799->addDeploymentScanner:817 {
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0436: Cannot register capability 'org.wildfly.management.deployment-scanner.dummy' at location '[
    (\"subsystem\" => \"deployment-scanner\"),
    (\"scanner\" => \"dummy\")
]' as it is already registered in context 'global' at location(s) '[[
    (\"subsystem\" => \"deployment-scanner\"),
    (\"scanner\" => \"dummy\")
]]'",
    "rolled-back" => true
} expected:<[success]> but was:<[failed]>
{noformat}

But it fails constantly on my machine, Is this the same cause appeared on CI ?

> I fear this has something to do with the capability registry and nothing to do with the scanner itself. It started happening when I added a capability to the scanner so it could consume a capability for the path it references.
> The test does a quick add/remove/add of a scanner resource and it's the 2nd add that fails with a dupicate capability error. But the remove mean the dup is gone. It's intermittent so I fear some race, but there's nothing obvious.
