Mark Miller commented on SOLR-5592:
-----------------------------------
You can have:
{noformat}
SolrCore Constructor
getSearcher
trigger first searcher listener asynchronously
warming queries, components, perhaps getSearcher
register JMX, perhaps getSearcher
{noformat}
> Possible deadlock on startup if using warming queries and certain components
> and jmx.

>
> Seeing the case with a spellcheck component.
> We attempt to register JMX properties after we open the first searcher in
> core init, but we can still have a race for the first searcher open because
> first we call getSearcher and it can trigger concurrent warming queries that
> can trigger components that call getSearcher.
