[Geoserver-users] Lots of classpath warnings in Jetty 9.4

Deploying GeoServer 2.16.1 to Jetty 9.4.24.v20191120, I get a lot of new Warnings in the log output when the server starts.

Here’s a sample of the errors. Full log attached. Seems like there are a lot of conflicting jars. javax.mail, activation, and various xml libs.

Its possible the reason this never came up before, is that default logging configs for Jetty changed between 9.3 and 9.4. We are just upgrading to 9.4 now, and have never seen this before.

Thanks Jason, that is good to know.

A quick search online[1] shows we may have accidentally include the servlet jar and need to work one maven excludes.
