Yes, JGroupsTransport wasn't failing x-site requests when the remote site
was unreachable: ISPN-9113 [1]

When I first started the migration away from MessageDispatcher I was hoping
to use the bridge view from RELAY2 to detect unreachable sites, but then I
realized only the site master sees the bridge view, so I went back to using
the SITE_UNREACHABLE event... or so I thought.

Cheers
Dan
