Hi!  Just wanted to let everyone know that we recently released a new
version of trapperkeeper-webserver-jetty9 to clojars.  The new version is
v1.2.0.

https://clojars.org/puppetlabs/trapperkeeper-webserver-jetty9

It's a feature release; there are a few new config options, but the most
significant change is that it bumps us up from a build of Jetty 9.1.x that
was about a year and a half old, to a much newer version (9.2.8).

The motivation for this was that we had a customer reporting a really
nasty, low-level Jetty race condition that could cause the server to end up
in a hung / deadlocked / unresponsive state after experiencing sustained
high load.  We were eventually able to reproduce the behavior in a test
environment and confirm that the newer version of Jetty fixes the issue.

We've also seen a marked improvement in startup time, which is a fairly big
deal for us since we spin up and shut down Jetty dozens and dozens of times
during the tests for our various trapperkeeper applications.  We have some
more targeted performance testing scheduled, but no results yet... but so
far, it seems quite a bit faster.

If you're interested in the gory details, see the CHANGELOG:

Thanks!
Chris
