When will JDK 9 builds move to requiring the boot JDK be JDK 8?

[Mike Duigou]

The general plan had been to wait until Java 8 was final before switching from JDK 7 to JDK 8. We planned switch internal Oracle build systems to JDK 8 after the April 15th CPU release. However, since there seems to already be a mix of JDK 7 and JDK 8 in use it is probably appropriate to switch now.

This caused problems when building jdk9/dev with a 7uX build as the boot JDK and made it obvious that there are a mix of boot JDKs in use (some people use 7uX, some use 8).
