Sigh, we do have a mismatch, I think a consequence of the churn last 
year on the design proposals. Note that javac and the run time are in 
sync so this doesn't impact anyone except when they start using the 
updated ASM to read/write module-info.class. I would like to get the 
spec updates that we are accumulating in jake into JDK 9 before JDK 9 
his ZBB and and right time to sort out the requires_flags too.
