[jboss-user] [Microcontainer] - @Depends and ObjectName key-value pair ordering

System details - JBoss-5 CR2, Sun Java 1.5, Windows 2003 Server OS

I have a @Service with a @Depends annotation as follows:

@Service (objectName = "vieo.ccs:service=Migration")
  | @Management(MyService.class)
  | @Depends({"jboss.jca:service=DataSourceBinding,name=DefaultDS"})
  | public class MyServiceImpl implements MyService {
  | .....
  | }

Nothing fancy with the implementation. When deployed on JBoss-5 CR2 this fails to deploy with a dependency error:

Note that the DefaultDS datasource binding has already been deployed. The jmx-console confirms this, under jboss.jca


If you notice closely, my @Depends annotation has a different order of key-value pairs (which as far as i know is valid for ObjectName) :


I then change my Service to change the key-value pair ordering to match what is seen in the jmx-console:


and this deploys fine. 

Isn't the ObjectName key/value pair supposed to be unordered? I tried to lookup the code responsible for this dependency management in the Microcontainer, but unfortunately this section of the documentation is still under construction. So i don't have much clue which piece of code is responsible for this.

P.S: I thought of posting this in the EJB3 forum but since this looks like a generic issue, i decided to post here. Let me know if this is not the right place.
