-------------------------------
I applied the patch to the code and when compiling the solr 1.4 code.. I'm
getting this:

> Unregistering of Searcher MBean doesn't work in Websphere
> ---------------------------------------------------------
>
> Key: SOLR-1841
> URL: https://issues.apache.org/jira/browse/SOLR-1841
> Project: Solr
> Issue Type: Bug
> Environment: Websphere Application Server 6.1
> Reporter: Patrik Nordebo
> Priority: Minor
> Attachments: patch, SOLR-1841.patch
>
>
> 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.
