Regression test sun/awt/image/BytePackedRaster/DitherTest.java fails intermittently
on Windows 2000 with JDK1.5.0 (tested with b24,b25) with the following message:

-------------------------------------------------
STATUS:Passed.
java.lang.NullPointerException: HDC for component
at sun.java2d.loops.DrawGlyphList.DrawGlyphList(Native Method)
at sun.java2d.pipe.SolidTextRenderer.drawGlyphList(SolidTextRenderer.java:36)

at DitherCanvas.setImage(DitherTest.java:366)
at DitherTest.run(DitherTest.java:234)
at java.lang.Thread.run(Thread.java:549)
-------------------------------------------------


With the following modification in DitherTest.main:

     public static void main(String args[]) {
         Frame f = new Frame("DitherTest");
         DitherTest ditherTest = new DitherTest();

         ditherTest.init();

         f.add("Center", ditherTest);
         f.pack();
         f.show();


         ditherTest.start();

         try{ Thread.sleep(1000); }catch(Throwable e){} // <== MODIFICATION

     }

the test always passes.

I cannot reproduce the failure with JDK1.4.2-b28. Nevertheless, since the modification
does not affect (in my opinion) the fix the test verifies, I'm filing the bug against the
test.
