Sharath Babu commented on SOLR-2927:
------------------------------------

SolrCore instantiates its SolrIndexSearcher asynchronously. If SolrCore hits an 
exception and closes *before* said SolrIndexSearcher is asynchronously opened, 
these mbeans will be registered *after* SolrCore clears its registry, so these  
mbeans would be leaked. 

> SolrIndexSearcher's register do not match close and SolrCore's closeSearcher

>    Affects Versions: 4.0-ALPHA

>            Reporter: tom liu

>
> # SolrIndexSearcher's register method put the name of searcher, but 
> SolrCore's closeSearcher method remove name of currentSearcher on 
> infoRegistry.
> # SolrIndexSearcher's register method put the name of cache, but 
> SolrIndexSearcher's close do not remove the name of cache.
> so, there maybe lost some memory leak.
