Drawing circles with drawArc() in XOR mode causes the circle
to appear dashed. This could occur if the end points of each
line segment overlap. Circles appear solid when not in XOR
mode. This is easy to reproduce, just draw a circle in XOR
mode and one not in XOR mode and compare. This didn't happen
in jdk1.3 (see comments)
