>
> Fix a leak of SolrIndexSearcher when a SolrCore is reloaded. Added a test to
> expose this leak when run in many iterations (pretty reliable failure with
> iters=1K), which passes with the fix (ran iters=10K twice).
> The fundamental issue is that when an invocation of SolrCore#openNewSearcher
> is racing with SolrCore#close, if this synchronized block
> (https://github.com/apache/lucene-solr/blob/master/solr/
> core/src/java/org/apache/solr/core/SolrCore.java#L1611) in openNewSearcher
> doesn't check for whether or not the core is closed, it can possibly run
> after the core runs closeSearcher and assign the newly constructed searcher
> to realtimeSearcher again, which will never be cleaned up. The fix is to
> check if the SolrCore is closed inside the synchronized block, and if so,
> clean up the newly constructed searcher and throw an Exception.
