Java HotSpot(TM) Client VM (build 1.4.1-beta-b14, mixed mode)


FULL OPERATING SYSTEM VERSION :
Microsoft Windows XP [Version 5.1.2600]


A DESCRIPTION OF THE PROBLEM :
When trying to paint a Compount Component (i.e. a Component
derived from Container that holds another component) in a
scaled graphics2D context, the following error occurs:

java.lang.IllegalStateException: constrain(xywh) is not
supported for complex tr
ansform.
        at sun.java2d.SunGraphics2D.constrain
(SunGraphics2D.java:295)
        
And painting is stopped.

REGRESSION. Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a class derived from Frame.
2. Override its paint method to scale the graphics context:
3. Create a simple compound component
4. add the compound component to the Frame
5. compile and run.

EXPECTED VERSUS ACTUAL BEHAVIOR :
The compound component is painted correctly (scaled) under
1.3 & 1.3.1 but causes an exception under 1.4 & 1.4.1
