Description

On a Websphere cluster, all MBeans registered in the default MBean server get renamed on registration (it adds properties based on which node and cell in the Websphere cluster the process was running). This means that when Solr tries to unregister an MBean (e.g. an old searcher), the old MBean is never removed. In the case of a rebind the binding of the new MBean fails because it tries to register a name that is already taken.

To get around this the name the mbean gets assigned must be stored somewhere where it can be looked up when we need to remove the binding.
