Review request: JDK8 b96 source with GPL header errors

[David Katleman]

Below are corrections to GPL headers errrors found in JDK8 b96
    http://cr.openjdk.java.net/~katleman/8019347/webrev/

Lion share are the recent jaxb update

All are punctuation issues, no code is involved, 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
