Hi Vicky, I updated to the trunk version yesterday and can not confirm this. Testing on Linux here. But I am glad you found that error as well. I am not sure if that error should be fixed like this. Right now a domain either can be in the JBoss or the platform MBean server. Is that intended or just a side effect of the implementation. My guess would be, that "combining" the two MBean servers should really behave like there would be only one MBean server. Does the spec say anything about that? Is that covered at all?
