-------------------------------------------------------------
I have been able to reproduce this issue patching the code to throw an exception in SolrCore in branch 4_2 in constructor line 875
...
resourceLoader.inform(resourceLoader);
//DO NOT COMMIT THIS:
if(!"metadata".equals(name)) throw new RuntimeException("test exception");
...
you can then curl any core
$curl "http://localhost:xxx/solr/CORE_NAME/select?q=*:*"
open a jconsole and you will see the leaking mbean named "solr/CORE_NAME"

> Key: SOLR-2927
> URL: https://issues.apache.org/jira/browse/SOLR-2927
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 4.0-ALPHA
> Environment: JDK1.6/CentOS
> Reporter: tom liu
> Assignee: Shalin Shekhar Mangar
> Fix For: 4.9, Trunk
>
>
> # 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.
