We added a special ALL-MODULE-PATH token to the -addmods option, with
this description now in JEP 261 (http://openjdk.java.net/jeps/261):

  As a further special case, if `<module>` is `ALL-MODULE-PATH` then all
  observable modules found on module paths are added to the root set.
  `ALL-MODULE-PATH` is valid at compile time when compiling classes in the
  unnamed module, and at run time when the main class of the application is
  loaded from the class path into the unnamed module.

This change is in Jigsaw EA build #4647 (https://jdk9.java.net/jigsaw/).
Please try it out and let us know what you think.
