I recently upgraded from Java 1.8.0_45 on OS X to Java 1.8.0_66 only to find that the rendered scene I'm working on now shows as inverted. I was able to fix the problem by rotating the camera 180 degrees, but I don't understand why I suddenly have to do this. I looked through the Java 8 SE release notes, but didn't spot anything that looked related to this. This seems like a new bug, but how can I know for sure?
On a related note, I find that Image texture maps applied to a PhongMaterial object show the image in the scene as being flipped from left to right. Is this also documented somewhere? Is there a control that I can use to flip how the texture is used, or am I expected to give the PhongMaterial class a reversed image? Here's a rendered scene showing the left/right reversal of a texture:
Note: text is not reversed in image used as texture map.

p.s. I've added some test code to demonstrate the first issue (inverted scene.) If you run the code under Java 1.8.0_45 on OS X, you'll get this:
But, run with Java 1.8.0_66 and you'll get this:
