[8u-60] request for approval to backport JDK-8080338, JDK-8080339, JDK-8080340: Incorrect GPL header causes RE script to miss swap to commercial header for licensee source bundle

[Jan Lahoda]

Hello,

I'd like to ask for an approval to backport the following fix to 8u-dev:

Bugs:
https://bugs.openjdk.java.net/browse/JDK-8080338
https://bugs.openjdk.java.net/browse/JDK-8080339
https://bugs.openjdk.java.net/browse/JDK-8080340

jdk9 fix:
http://hg.openjdk.java.net/jdk9/dev/langtools/rev/8bc4c0b6eeb7

The fix applies cleanly to 8u-dev/langtools.

Thanks,
     Jan
