Review request for MACOSX_PORT-785: painting artifacts after running SwingSet2 with jdk7u-osx build

[Dmitry Cherepanov]

Hello,

Please review a fix for http://java.net/jira/browse/MACOSX_PORT-785 at

http://cr.openjdk.java.net/~dcherepanov/7125723/webrev.0

The fix suggests pushing the following changeset [1] (that was missed 
after syncing from macosx-port to jdk7u-osx) to jdk7u-osx.

Thanks,
Dmitry
