RFR(s): 8186851 fix misspellings of "dependent" and "independent" in the JDK repo

[Stuart Marks]

Hi all,

I was irked by some misspellings so I decided to create a quick fix.

Webrev:

    http://cr.openjdk.java.net/~smarks/reviews/8186851/webrev.0/

Bug:

    https://bugs.openjdk.java.net/browse/JDK-8186851

Most of the changes are in core libs and in Swing, so I'm posting to both lists.

Thanks,

s'marks
