Request for approval to backport 7072645: "Toolkit.addPropertyChangeListener(name, pcl) throws NPE for null name" to jdk7u-dev/jdk

[Denis S. Fokin]

Good day.

I hereby request to approval to backport

7072645: Toolkit.addPropertyChangeListener(name, pcl) throws NPE for 
null name
http://hg.openjdk.java.net/jdk8/awt/jdk/rev/7968d9677f9a

to jdk7u-dev/jdk.

This is a direct backport of the change. The fix has been reviewed by 
art and JCK team (Dmitry Bessonov).

Thank you,
       Denis.
