`javac --add-modules ALL-SYSTEM` doesn't currently resolve incubator modules and needs to be re-examined. The equivalent at runtime (`java --add-modules ALL-SYSTEM`) has been changed in jake to not ignore incubator modules and so is now consistent with ModuleFinder.ofSystem() which will find all observable modules.

This issue might require looking at ALL-MODULE-PATH too, this should resolve all modules on the module path and should not cause incubator modules in the system image to be resolved.
