[jboss-jira] [JBoss JIRA] (AS7-1996) Unsuccessfull deployment-scanner:add operation changes runtime state

[Brian Stansberry (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1996?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12632158#comment-12632158 ] 

Brian Stansberry commented on AS7-1996:
---------------------------------------

My assumption is the rollback logic for the "add" operation is failing to fully clean up, so the MSC service created for the path is left around.

>                 URL: https://issues.jboss.org/browse/AS7-1996
>             Project: Application Server 7
>          Issue Type: Bug
>          Components: Domain Management
>    Affects Versions: 7.1.0.Alpha1
>            Reporter: Dominik Pospisil
>            Assignee: Brian Stansberry

> Steps to reproduce:
> 1) Start standalone server
> 2) Issue:
> /subsystem=deployment-scanner/scanner=testScanner:add(scan-interval=2000,path="/noexisiting")
> where /noexisting is some incorrect path
> 3) Issue:
> /subsystem=deployment-scanner/scanner=testScanner:add(scan-interval=2000,path="/tmp/test")
> where /tmp/test is a valid path
> I think that the expected result would be that the step 2 fails and it does not affect runtime nor configuration model.
> The result of step 3 should be then a success however it is actually a failure:
> 08:45:25,421 ERROR [org.jboss.as.controller] (pool-3-thread-8) Operation ("add") failed - address: ([
>     ("subsystem" => "deployment-scanner"),
>     ("scanner" => "testScanner")
> ]): org.jboss.msc.service.DuplicateServiceException: Service jboss.server.deployment.scanner.testScanner.path is already registered
