I'm sure that's right.  However, we are also running the risk of
breaking important use cases when JDK9 is released.  We're going to
have to do a lot of work with developers to make sure that they can
still work with JDK9.  The problem is that many developers do not even
try to run with a new JDK until that JDK is released.  So, we have to
make sure that we have enough escape hatches.
