> Pre 4.10 If a null core name was passed in it would be handled as a bad request with error message "No such core exists [ null ]". From 4.10 onwards an unload call goes to CoreContainer unload where the first action taken is removing the core from coreInitFailures which throws when given null and instead of returning the expected BadRequest "Cannot unload non-existent core [null]" it returns InternalServerError "java.lang.NullPointerException
> at java.util.concurrent.ConcurrentHashMap.replaceNode(Unknown Source)
> at java.util.concurrent.ConcurrentHashMap.remove(Unknown Source)
> at org.apache.solr.core.CoreContainer.unload(CoreContainer.java:661)..."
> This was found due to mixing up query parameter "name" used in create vs "core" in unload. As a result this is easily reproducible with http://localhost:8983/solr/admin/cores?action=UNLOAD&name=core0
