Yes, this works.
The MyLibrary is compiled with -modulesourcepath src to make MyLibraryTests
module resolvable from MyLibrary’s module-info.

I believe that they do not have package private dependencies. And the packaging
comes historically from the source layout. The sources are in the same package
and then packed into ant-junit (the optional JUnitTask and Ant’s test runner)
ant-junit4 (containing just the Adapter from JUnit 4 API to Ant 3.8 API).

Thanks Alan, it’s good to know this. These two jars are Ant implementation
details, they were always put on classpath by Ant. I will try to keep them in
the UNNAMED-MODULE. There is no need to
make them automatic modules because no one depends on them, they are only a
test launcher.
