[zeitlinger]

Created by copying the servlet 3 tests and then applying the diffs from between the groovy servlet 3 and groovy servlet 5 tests

@laurit do I need to create a jetty11 testing project to get rid of this?

We have two kinds of modules that are named testing. Firstly there are module that contain classes that are shared by multiple modules that contain tests, e.g. a common testing module for javaagent and library modules. Secondly we have modules that contain the tests because for whatever reason they can't be in the same module as the instrumentation. I don't think we ever mix the two purposes. You could also do the same here by keeping the testing module as shared code and moving the tomcat tests together with instrumentation or to a separate module.
