[Clustering/JBoss] - Re: Forcing Topology change

I tried Jgroups 2.3SP1 ( I didn't see 2.3 sp2 in sorceforge) and it works!
Stop and start of partition is working across node1 and node2. However I see a behavior that is probably a bug.
So I have 10.0.1.61 and 10.0.1.62 in a cluster with 10.0.1.61 as Master.
I close partition on 10.0.1.61. 10.0.1.62's current view changes to contain just itself and becomes Master.
However 10.,0.1.61's current view still has [10.0.1.61. 10.0.1.62] although the Master flag is false in SingletonController.
Shouldn't the current view be reset in 10.0.1.61 when it leaves the partition?
Now I start partition on 10.0.1.61. It initially starts a new view with itself and does a merge with 10.0.1.62. However instead of 10.0.1.62 becoming Master. It remains a master. Since 10.0.1.61 left the partition , shouldn't it have come up as non master ? Also it is receiving a membershipChanged event with 10.0.1.62 as dead member. I couldn't understand this. I'll try the scenario with UDP as well to see if both behaves similarly.
Below is the server log
