> For OS X, it looks like {{webAppContext.setBaseResource}} and accessing the sources from a jar file will cause {{file.resource.toURI().getPath()}} to return {{null}} for {{jar:-urls}}
> I checked that changing the jetty-version from {{9.4.20.v20190813}} to something above {{9.4.21}} (aka., 9.4.23.v20191118) fixes the warning.

> Do you guys think we should consider upgrading Jetty to the [latest versions of 9.4.x|https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-webapp] like 9.4.35?
