The javax.annotation package should be renamed to javax.anarchy :-)

Hopefully we will have builds soon that implement the new policy for the 
root modules when the initial class is on the class path. That will mean 
that java.annotations.common will not be resolved by default and should 
help here.

The interface is visible but its package isn't exported by the module to 
everyone that potentially reads the module. This is subtle but 
-XaddExports exports packages to specific targets. The "ALL-UNNAMED" 
token is all unnamed modules, it's not all modules.
