---------------------------------
I tried reproducing again in the testsuite but no luck. Can you give an example or point me towards the code that makes this happen?

> Key: AS7-5794
> URL: https://issues.jboss.org/browse/AS7-5794
> Project: Application Server 7
> Issue Type: Bug
> Components: Domain Management, JMX
> Affects Versions: 7.1.2.Final (EAP)
> Reporter: Tristan Tarrant
> Assignee: Kabir Khan
> Fix For: 7.3.0.Alpha1

> When issuing MBean queries over JMX remoting, the AS is returning a list of org.jboss.as.controller.ModelController objects in addition to those matching the query.
> This is a transcript of a chat we had about it on IRC:
> Oct 15 14:51:46 <ttarrant> darranl, if I issue a jmx query over jmx-remoting I get many more objects than expected
> Oct 15 14:51:55 <ttarrant> darranl, i.e. ones that do not match the query
> Oct 15 14:52:09 <ttarrant> darranl, this is with 7.1.x
> Oct 15 14:52:57 <ttarrant> darranl, this works if I use the standard JMX over RMI
> Oct 15 14:53:08 --> fnasser (~fnasser(a)CPE602ad07ab726-CM602ad07ab723.cpe.net.cable.rogers.com) has joined #jboss-as7
> Oct 15 14:53:09 <-- fnasser has quit (Changing host)
> Oct 15 14:53:09 --> fnasser (~fnasser@redhat/jboss/fnasser) has joined #jboss-as7
> Oct 15 14:53:09 --- ChanServ gives voice to fnasser
> Oct 15 14:53:16 <ttarrant> darranl, do you just pass the query the the mbeanserver ?
> Oct 15 14:53:39 <darranl> ttarrant: what kind of objects? within AS7 I think there are two things that could affec
> t this 1 - The Remoting JMX protocol, 2 - The domain management representation over JMX
> Oct 15 14:53:54 <darranl> For #1 yes we just pass it to the MBEanServer and return whatever it returns
> Oct 15 14:54:04 <darranl> if it was a Remoting JMX bug maybe we are messing up the query
> Oct 15 14:54:16 <ttarrant> darranl, the query is as follows: *:type=CacheManager,component=Interpreter,name=*
> Oct 15 14:54:16 <darranl> But not sure if #2 could be the reason more is getting added
> Oct 15 14:54:32 <ttarrant> darranl, wait a sec
> Oct 15 14:54:57 <darranl> ttarrant: I would suggest getting a Jira raised and assigned to me, I can verify if it i
> s a remoting jmx issue or pass over if it is a domain management integration issue
> Oct 15 14:55:20 <darranl> regardless of where it is happenign it sounds like you may have discovered a bug
> Oct 15 14:56:23 <ttarrant> darranl, let me get the objects it's returning
> Oct 15 14:56:39 <darranl> ttarrant: when you enable the RMI approach you bypass both Remoting JMX AND the domain m
> anagement integration
> Oct 15 14:56:42 <darranl> ok
> Oct 15 15:26:08 <ttarrant> darranl, ok, my query actually returns the object I queried for and a bunch of org.jboss.as.controller.ModelController (one for each subsystem)
> Oct 15 15:51:24 <darranl> ttarrant: ok that does then sound like it is the domain management integration that is 'poluting' the query results
> Oct 15 15:51:53 <darranl> ttarrant: going RMI was just bypassing that as well
> Oct 15 15:52:05 <ttarrant> darranl, shall I open a Jira ?
> Oct 15 15:52:34 <ttarrant> darranl, I work around the issue by manually filtering the returned objects based on class name
> Oct 15 15:53:23 <darranl> ttarrant: it would probably be one for kkhan to look into, think he is just back today so may be worth the Jira so he can have a look once he has caught back up ;-)
