[joe darcy]

Hello,

A fix for

     JDK-8129909: Add -Xdoclint/packages: to javadoc
     https://bugs.openjdk.java.net/browse/JDK-8129909

is working its way through the system, in anticipation of that fix, 
please view my fix for

     JDK-8080722: Revisit how to check for doclint reference warning 
during the build

Patch below:

As discussed on jdk9-dev, this fix will allow JEP 212 to be completed.

Just to be clear, I would not push the fix for JDK-8080722 until the fix 
for JDK-8080722 is in the jdk 9 dev forest. Additionally, I'll verify 
the build still works at that point with the patch above.

Thanks,
