Description

As reported by a user, if you use the PingRequestHandler, and the corrisponding helthcheck file doesn't exist (and expected situation when a server is out of rotation) Solr is logging a SEVERE error...

SEVERE: org.apache.solr.common.SolrException: Service disabled

This is in spite of hte fact that PingRequestHandler explicitly sets the "alreadyLogged" boolean to true in the SolrException constructor.
