can't build jigsaw with new javac

[Jonathan Gibbons]

Uuugh.   Well, you've got a mixed up world with the classes in a 
classes/ hierarchy and the module-info files in a modules hierarchy 
under tmp/modules/src.  On top of which you've got an empty directory on 
modulepath and no -d. No wonder javac is confused ;-)

It would seem that we either have to resolve the conflict between the 
classes/ and module-info hierarchies, or we have to revisit the decision 
to forbid use of bootclasspath with module compilation for javac.
