2.x/examples/osgi-helloworld-webapp does not work with Jetty 12 but with Jetty 10

## Background
I'm trying to migrate some legacy code from Jetty 10 to Jetty 12.
I'm using Jetty 12 ee8 and Jersey 2.x.

## Issue

https://github.com/eclipse-ee4j/jersey/tree/2.x/examples/osgi-helloworld-webapp does work with Jetty 10 but not with Jetty 12.

See https://github.com/jetty/jetty.project/issues/11315
