The modules owned by Java EE are not resolved by defaulted in JDK 9, see 
the section on "Root Modules" in JEP 261 [1] for more details on that, 
also the "Risks and Assumptions" for more of the rational.

In this case, you can run with `--add-modules java.activation` or else 
put activation.jar on the class path.
