Rajkumar Rajaratnam commented on STRATOS-849:
---------------------------------------------
Hi Akila,
There is no problem with ClusterMonitorFactory at all.
isLbCluster attribute of cluster object is true for jboss cluster. Hence
the factory is creating lb cluster jboss. We are looking into where the
isLbCluster was set to true for jboss.
Thanks.

> It seems service instance is also created by VMLbClusterMonitor. This is
> wrong. This should be fixed in ClustorMonitorFactory class.
