JDK 9 RFR and sponsorship of JDK-8030656 Bad version check for parameter information in src/share/vm/classfile/javaClasses.cpp

[Joe Darcy]

Hello,

During the course of trying to increment the JDK_MINOR_VERSION from 8 to 
9 in the JDK 9 forest, a HotSpot bug has discovered:

         JDK-8030656 Bad version check for parameter information in 
src/share/vm/classfile/javaClasses.cpp

Fortunately, the fix is very simple:

    // generated interpreter code wants to know about the offsets we 
just computed:

With this patch, the java.lang.reflect.Parameter related tests that fail 
in the jdk and langtools repos pass.

I'm requesting review of and sponsorship of this fix for JDK 9.

Thanks,
