Confirmed:
* useAA=true:
sun.java2d.marlin.MarlinRenderingEngine.getAATileGenerator(java.awt.geom.Line2D$Double, AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]], Region[[0, 0 => 400, 400]], java.awt.BasicStroke at 110e1781, wide, normalized)
* useAA=false:
sun.java2d.marlin.MarlinRenderingEngine.strokeTo(java.awt.geom.Line2D$Double, AffineTransform[[1.0, 0.0, 0.0], [0.0, 1.0, 0.0]], Region[[0, 0 => 400, 400]], java.awt.BasicStroke at 110e1781, wide, normalized, non-AA, sun.java2d.pipe.ShapeSpanIterator)
