-----------------------------------
Well, at least they are repeatable fails.
Not sure what it is yet, but fails seem to have the following that I don't see
in passes:

> Upgrade Jetty from 9.2 to 9.3
> -----------------------------

> Key: SOLR-7339
> URL: https://issues.apache.org/jira/browse/SOLR-7339
> Project: Solr
> Issue Type: Improvement
> Reporter: Gregg Donovan
> Assignee: Mark Miller

> Jetty 9.3 offers support for HTTP/2. Interest in HTTP/2 or its predecessor
> SPDY was shown in [SOLR-6699|https://issues.apache.org/jira/browse/SOLR-6699]
> and [on the mailing list|http://markmail.org/message/jyhcmwexn65gbdsx].
> Among the HTTP/2 benefits over HTTP/1.1 relevant to Solr are:
> * multiplexing requests over a single TCP connection ("streams")
> * canceling a single request without closing the TCP connection
> * removing [head-of-line
> blocking|https://http2.github.io/faq/#why-is-http2-multiplexed]
> * header compression
> Caveats:
> * Jetty 9.3 is at M2, not released.
> * Full Solr support for HTTP/2 would require more work than just upgrading
> Jetty. The server configuration would need to change and a new HTTP client
> ([Jetty's own
> client|https://github.com/eclipse/jetty.project/tree/master/jetty-http2],
> [Square's OkHttp|http://square.github.io/okhttp/],
> [etc.|https://github.com/http2/http2-spec/wiki/Implementations]) would need
> to be selected and wired up. Perhaps this is worthy of a branch?
