Found the problem! Just in case anyone encountered the same problem.
The issue was that the the jerser-server (v2.31) had a dependancy on
jetty-server (v9.4.27), and we were configured with jetty-server
(v9.4.31).
Thank you all for your help.

It worked at some point and then suddenly when I structured the folder
holing the webapp I just started getting these errors. I am running
jetty embedded, and launch both an angular web application
(ContextHandler), and also a servlet (createServletContextHandler), and
using adding them to a ContextHandlerCollection.

Hello
I use Jetty with Jersey, I have no such problems, you can have a look
at my project, maybe it could help you:
https://sourceforge.net/projects/red-feed-aggregator/
I think that a dependency is missing in your pom file.

Hello,
I am new to Jetty and have seen some inconsistent behavior that I am
struggling to find the cause. I am using the embedded jetty via a
maven dependency file that is shown below. I am trying to use the the
jersey container to support webservice annotations.

I sometimes encounter no problems, and sometime struggle for with the
following exception!
