Review request: JDK8 b89 source with GPL header errors

[David Katleman]

Below are corrections to GPL headers found in JDK8 b89:

     http://cr.openjdk.java.net/~katleman/8014289/webrev.jdk.01/

Just 4 files this go around, all are simple punctuation changes, anyone 
can review.

As a veteran of many such header reviews, reviewing the patch link at 
the top of the webrev is often easier than each individual file.

         Thanks
                 Dave
