That wasn't quite my query/concern - I wasn't very clear. If someone is 
doing a partial build, ie JDK repo only, they will now have to use a 
JDK8 boot JDK (or point to suitable langtools import?) - correct? (Where 
a full build would use the current langtools to build the rest of the JDK.)

Just trying to understand if there may be places (JPRT?) where we've so 
far been able to use a JDK7 boot JDK but will no longer be able to.

Thanks,
David
