<AWT Dev> [7] Review Request for 8001633: Wrong alt processing during switching between windows.

[mikhail cherkasov]

Hello all,

Could you please review a backport to jdk7 for the following bug:

bug: https://bugs.openjdk.java.net/browse/JDK-8001633
Webrev: http://cr.openjdk.java.net/~mcherkas/8001633/jdk7/webrev.00/
review for jdk8: 
http://mail.openjdk.java.net/pipermail/awt-dev/2012-October/003732.html

It's direct backport except a test case, the test case was replaced with 
a new one, because
jdk8's test case doesn't reproduce the problem for jdk7.

Thanks,
Mikhail.
