I am struggling with a Java / Maven / Jetty problem that I cannot solve. I have a Java Jetty server that starts up correctly, but as soon as an HTTP request is sent to it, it stops showing this stacktrace:

It’s clear that there is something strange in the jars included for launch, and on Google I can find some links to this problem, but without a clear solution.
