Re: [jetty-users] Vert.x-like functionality in Jetty?

Not to mention two of the systems you call out in your signature, Solr
and Hdfs, use jetty (solr as part of a distro I think and hdfs as the
http server used to serve ranges of files around down in its guts)

google app engine and gwt uses jetty under the covers as well...

but your on a jetty mailing list will get responses biased
towards jetty :)
