FULL PRODUCT VERSION :
java version "1.4.0-rc"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-rc-b91)
Java HotSpot(TM) Client VM (build 1.4.0-rc-b91, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]



EXTRA RELEVANT SYSTEM CONFIGURATION :
bug appears also in beta3 but not in beta1 or beta2 and not
in any 1.3 versions.

A DESCRIPTION OF THE PROBLEM :
BufferedImage TYPE_USHORT_565_RGB do not copy green and red
channel

REGRESSION.  Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I create a BufferedImage with

Image Image1 = new BufferedImage(getWidth(), getHeight(),
> BufferedImage.TYPE_USHORT_565_RGB);

and paint something (he flag of the RGB country) this
BufferedImage with :
> Graphics2D Graphics1 = (Graphics2D)Image1.getGraphics();
> Graphics1.setColor(Color.blue);
> Graphics1.fillRect(0, 0, getWidth(), getHeight()/3);
> Graphics1.setColor(Color.red);
> Graphics1.fillRect(0, getHeight()/3, getWidth(), getHeight
()/3);
> Graphics1.setColor(Color.green);
> Graphics1.fillRect(0, 2*getHeight()/3, getWidth(),
getHeight()/3);

before beta3 it worked with all kind of bufferedImages
(i.e.TYPE_INT_RGB) but TYPE_USHORT_565_RGB looked more
performant as I paint later produced image in an other
bufferedImage USHORT_565_RGB.
Now all the others bufferedImage continue to work and look
faster but this one is not working anymore (only the blue
works and the green and red are transparent). Once angain I
have others versions of java installed on my computer and
the same code (not recompiled) works with 1.3.1, 1.4beta2
but not with beta3 and RC1.

EXPECTED VERSUS ACTUAL BEHAVIOR :
I expected the green to be green and the red to be red.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
no error message

This bug can be reproduced always.

    JFrame1.getContentPane().setLayout(new BorderLayout());
    JFrame1.getContentPane().add(JComponent1);
    JFrame1.setSize(200, 200);
    JFrame1.show();
  }
}

CUSTOMER WORKAROUND :
I use an other type of BufferedImage because I don't care
the type but others peoples may need a well defined
BufferedImage type

Release Regression From : 1.3.1_02
The above release value was the last known release where this 
bug was known to work. Since then there has been a regression.
