Subject [jira] [Created] (SOLR-9117) Leaking the first SolrCore after reload

------------------------------------------

             Summary: Leaking the first SolrCore after reload
                 Key: SOLR-9117
                 URL: https://issues.apache.org/jira/browse/SOLR-9117
             Project: Solr
          Issue Type: Bug
            Reporter: Jessica Cheng Mallet
         Attachments: SOLR-9117.patch

When a SolrCore for a particular index is created for the first time, it's added to the SolrCores#createdCores
map. However, this map doesn't get updated when this core is reloaded, leading to the first
SolrCore being leaked.

Taking a look at how createdCores is used, it seems like it doesn't serve any purpose (its
only read is in SolrCores#getAllCoreNames, which includes entries from SolrCores.cores anyway),
so I'm proposing a patch to remove the createdCores map completely. However, if someone else
knows that createdCores exist for a reason, I'll be happy to change the fix to updating the
createdCores map when reload is called.
