This problem is found on both Windows and Solaris.
Build tested: B89

The problem has been there since B75 and hence it's a regression
It worked fine till B74.

Steps to reproduce the problem:

1. Launch Java2Demo
2. Click on Arcs_Curves tab
3. Select BYTE_BINARY as the buffered image in the drop down box under
   Global Controls
4. Monitor the 3rd quarter (bottom left) with 3 curves for each QuadCurve2D
   and CubicCurve2D.
5. Turn anti-aliasing off and you will find the middle curve missing.

It works fine for any other buffered image type.
There was a bug 4358146 filed related to anti-aliasing on Java2Demo, long back.

We tested on Win2K and Sparc 7 and the bug is there in both.
Haven't tested with Linux yet.
