Hi, I recently tried to track down JDK-8156100 (xrender: Subpixel drawing bug in Java 8) - under some circumstances paths do not align with fills when subpixel coordinates are used. The issue seems to be caused by ProcessPath and ShapeSpanIterator behaving differently with regards to rounding.
I've created a small testcase to illustrate the issue: http://pastebin.com/hy5zCkPR - where a rectangle with subpixel coordinates is "drawn" with bothl, SSI and ProcessPath. The ShapeSpanIterator seems to truncate any subpixel values, whereas ProcessPath always seems to "round up". Is this expected behaviour? Should I avoid SSI and switch to ProcessPath entirely? Thank you in advance, Clemens
