Subject [jira] Updated: (SOLR-509) Event Listeners called before request handlers are informed of SolrCore

Yonik Seeley updated SOLR-509:
------------------------------

    Attachment: SOLR-509-fix.patch

Here's the latest version, which restores firstSearcher event handling to getSearcher, and
uses a latch to block any searcher warming events until the end of the SolrCore constructor.

> Thijs noticed NullPointerException from SearchHandler on startup when trying to configure
some firstSearcher events using QuerySenderListener.
> The problem is the events are getting triggered as soon as the firstSearcher is opened,
but the SOlrCore isn't finished being initialized, so inform(SolrCore) hasn't been called
on all the Handlers (and some handlers aren't fully initialized and ready to process requests
yet.
> We need to more the firstSearcher event handling after inform has been called on all
SolrCoreAware objects.
