Run Java2Demo on any system  with the  Xrender pipeline is enabled (Solaris
or Linux) and navigate to the Fonts tab and look at the "highlighted" text.
In AA mode this appears all black.

EVALUATION I now notice it also on Windows, but only as a missing texture background on java2d.demos.Paint.Texture tab.

EVALUATION This also affects the java2D demo clipping.Areas tab - again only in AA mode. It looks like the forward port in to JDk 7 b126 of 6766342: Improve performance of Ductus rasterizer has a typo such that the AA tile generator is told this is a fill rather than a draw. Interesting that its only visible with the Xrender pipeline.
