JDK version: 8u71 b05
OS: Ubuntu 14.04
Platform: ARMv7
Reproducibility: always

It could be a dupe of JDK-8079255. If so, then SQE will request a backport to 8u72.
Comments
The issue is platform-specific with narrow usage. I believe apps are not affected with the reversed rotation. No plans to address unless a business/other case exists.

It could be a dupe of JDK-8079255. But I'm afraid backporting it won't fix this issue on embedded: that fix addresses Mac OS. When it's run on embedded Linux, the test wouldn't negate the value of wheelRotation. Therefore the test will still fail.

Moving to 16_03 so we can take a decision on platform support as referenced by Victor above.

Moving to 16_02

We don't test jdk 9 on embedded.

Does it affect 9 ?
