v51 class files

I agree, but it has been convenient to allow a grace period for Jigsaw 
development to allow the rest of the tools to catch up with support for 
v52.    So, the question is, are we ready to end the grace period and 
convert to using v52 class files in normal use?    Who gets to make that 
decision, and who gets to coordinate the change?

And, since Jigsaw is now targeted for JDK 9, and defines attributes that 
will presumably not be in Java 8, should Jigsaw start moving towards v53 
class files?
