Jason Gerlowski commented on SOLR-16615:
----------------------------------------
Yes, that was definitely from a commit I merged this morning [~hossman]. I'm
reverting and looking into the failure now. Of course the tests pass for me
locally.

> Key: SOLR-16615
> URL: https://issues.apache.org/jira/browse/SOLR-16615
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Jason Gerlowski
> Priority: Minor
> Labels: API, performance
> Time Spent: 1h 50m
> Remaining Estimate: 0h
>
> Currently, each core parses solrconfig.xml and instantiates its own copy of
> various plugins (v2 'Api' instances, RequestHandlers, etc.) or plugin-related
> objects (e.g. Jersey "ApplicationHandlers").
> Usually this is fine, but when many cores on a Solr node share the same
> configset, this duplication can become wasteful and have considerable impacts
> on node startup and core reload time.
> We should investigate whether some of these solrconfig.xml-driven entities
> can be shared by cores with the same configset that live in the same JVM.
