public class SolrSmokeTest
extends Object
Spin off a thread that will try to connect to Solr.
We need to do this in a separate thread because if Solr is in the same Tomcat
instance as Vitro, it may not be initialized until after Vitro is
initialized. Which is to say, after this Listener has run.
If we can't connect to Solr, add a Warning item to the StartupStatus.
