[jdk8u-dev] RFR: 8129827: [TEST_BUG] Test java/awt/Robot/RobotWheelTest/RobotWheelTest.java fails

[Joshua Cao]

Parity with Oracle. This patch is applied on top of https://github.com/openjdk/jdk8u-dev/pull/140. Does not apply cleanly, mostly due to surrounding context missing from the following:

* https://bugs.openjdk.org/browse/JDK-8210039 (don't think there are plans to backport this to JDK8)
* https://bugs.openjdk.org/browse/JDK-8159690 (open issue to backport this to 8, but has not been active for >1 year. might get backported)

Only one serious conflict. We cannot use


private static int wheelSign = Platform.isOSX() ? -1 : 1;


Since https://bugs.openjdk.org/browse/JDK-8210039 is missing in JDK8, we don't have 


import jdk.test.lib.Platform;


Alternatively, I use the old code to get OS:


private static int wheelSign = OSInfo.getOSType().equals(OSInfo.OSType.MACOSX) ? -1 : 1;
