[11u] RFR: 8211825: ModuleLayer.defineModulesWithXXX does not setup delegation when module reads automatic module

[Doerr, Martin]

Hi,

JDK-8211825 is backported to 11.0.11-oracle. I'd like to backport it for parity.
The original change applies cleanly, by javac from 11u has a problem with the new AutomaticModulesTest:
AutomaticModulesTest.java:70: error: reference to createJarFile is ambiguous
        JarUtils.createJarFile(LIB.resolve("alib.jar"), CLASSES);
                ^
  both method createJarFile(Path,Path,Path...) in JarUtils and method createJarFile(Path,Path,String...) in JarUtils match

I suggest to resolve it this way:
