This is due to a bug in Jetty 9.4.11:
https://github.com/eclipse/jetty.project/issues/2233#issuecomment-404082685
This has been fixed in 9.4.12:
https://github.com/eclipse/jetty.project/commit/17b6eee5aca00460913a2b7847325b6e3df39fd2
So bumping our Jetty version should prevent future occurrences of this.
