      Description

      We should disable SSLv3 in HttpFS to protect against the POODLEbleed vulnerability.
      See CVE-2014-3566

      We have sslProtocol="TLS" set to only allow TLS in ssl-server.xml, but when I checked, I could still connect with SSLv3. There documentation is somewhat unclear in the tomcat configs between sslProtocol, sslProtocols, and sslEnabledProtocols and what each value they take does exactly. From what I can gather, sslProtocol="TLS" actually includes SSLv3 and the only way to fix this is to explicitly list which TLS versions we support.
