<AWT Dev> Review Request for 6879044

[Mandy Chung]

Here are the new webrevs:

core-libs changes that include java.util.Currency:
    http://cr.openjdk.java.net/~mchung/6882376/webrev.00/

    - Added a new jtreg test
    - Cleaned up PlatformLogger.java per Alan's feedback.

awt/2d/swing changes:
    http://cr.openjdk.java.net/~mchung/6879044/webrev.01/

    - Keep the logger in AWTEvent.java and Cursor.java be statically 
initialized.
    - I updated 6880089 to consider lazy initialization or reduce to a 
few loggers vs 85 on unix and 35 on windows.  I decide to leave it to 
the fix for 6880089 to make a consistent change.

Files other than the one listed above are not changed since the last 
version.

Thanks
Mandy
