Description

While I was looking into TestDistributedShell logs, I noticed the following Warning

2020-12-29 16:22:26,379 INFO  [Time-limited test] handler.ContextHandler (ContextHandler.java:doStart(824)) - Started o.e.j.s.ServletContextHandler@75389179{logs,/logs,file:///hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-distributedshell/target/log,AVAILABLE}

2020-12-29 16:22:26,390 WARN  [Time-limited test] webapp.WebInfConfiguration (WebInfConfiguration.java:getCanonicalNameForWebAppTmpDir(794)) - Can't generate resourceBase as part of webapp tmp dir name: java.lang.NullPointerException
2020-12-29 16:22:26,469 INFO  [Time-limited test] util.TypeUtil (TypeUtil.java:<clinit>(201)) - JVM Runtime does not support Modules

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 like 9.4.35?
