How to increment JDK_MINOR_VERSION for JDK 9?

[Joseph Darcy]

Hello,

Looking ahead to JDK 9, a build 01 change that is needed is updating the 
JDK_MINOR_VERSION setting in the build from "8" to "9":

        JDK-8000962 Update JDK_MINOR_VERSION for JDK 9
        https://bugs.openjdk.java.net/browse/JDK-8000962

I poked around a bit, but didn't see where this needs to be set. The 
value of this variable gets used in numerous places throughout the JDK, 
including in system properties.

How can this be updating in the new build?

Thanks,

-Joe
