Request for Approval - 8u20 backport - REGRESSION: test/closed/javax/swing/AbstractButton/4246045/bug4246045.java fails

[Pete Brunet]

Hi,  I'm requesting approval of a 9 to 8u20 backport.

8u bug:  https://bugs.openjdk.java.net/browse/JDK-8043901
9 bug:  https://bugs.openjdk.java.net/browse/JDK-8009883
9 changset:  http://hg.openjdk.java.net/jdk9/client/jdk/rev/4ac8cec7ff40

The changeset applies cleanly and a test shows no issues.

Thanks, Pete
