Erick Erickson updated SOLR-5366:
---------------------------------

    Attachment: SOLR-5366.patch

Building on Olivier's patch. I think there was a race condition possible (but unlikely) where the close could be pending on the transient core, so I changed the code a bit to avoid that.

Thanks Olivier!

Committing to trunk momentarily, 4x a in a bit.

> To reproduce :
> set transientCacheSize=2 and start with no cores
> Create 3 cores :
> curl "http://ip:port/solr/admin/cores?action=CREATE&name=coreX&instanceDir=path_to_instanceDir_coreX&dataDir=path_to_dataDir_coreX&loadOnStartup=false&transient=true"
> Execute :
> curl "http://ip:port/solr/core1/select?q=*:*"
> curl "http://ip:port/solr/core2/select?q=*:*"
> curl "http://ip:port/solr/core3/select?q=*:*"
> curl "http://ip:port/solr/admin/cores?action=UNLOAD&core=core1"
> And in Solr logs :
> ERROR org.apache.solr.core.SolrCore  – Too many close [count:-1] on org.apache.solr.core.SolrCore@20e5ace9. Please report this exception to solr-user@lucene.apache.org
