Hoss Man resolved SOLR-1843.
----------------------------

         Assignee: Hoss Man
    Fix Version/s: 1.5
       Resolution: Fixed

Committed revision 942292.

Constantijn: thanks for this suggestion.  The one significant change i made 
from your original files (BTW: a patch would have been much easier to review) 
is that i made the "rootName" option completely replace the previous default: 
"solr/" + coreName (as opposed to your version where only the "solr" literal 
was was replaced by the rootName)

Since this lives in solrconfig.xml it's a core specific setting, and core 
properties can be used to include the coreName in the rootName if that's what 
people desire

> When i run multiple independent SOLR webapps both with JMX enabled there 
> seems to be some sort of collision when registering Mbeans causing my 
> application server to throw exceptions for each mbean it tries to register 
> for all applications after the first.
> This seems to be due to collision issue of sorts with both applications 
> trying to register their mbeans under the name "solr"
> This patch fixes the issue by allowing the user to specify the name under 
> which MBeans are registered in solrconfig.xml like so:
>   <jmx rootName="mySolr" /> 
> i went with rootName since in the code the variable is called jmxRootName.
