Hi Alan,

To contribute a little to the small nit picking process :) :

1. src/share/classes/javax/swing/JPopupMenu.java
Line 415 might be realigned to keep standard indentation.

2. The copyright notices might be updated to indicate that 2009 is the 
year of last modification of the files.

The rest looks good. Please consider that approved by the AWT team.

best regards,
