[Bug awt/26618] New: Graphics(2D) type hierarchy broken?

[hendrich at informatik dot uni-hamburg dot de]

Sorry. I think I have a blackout here...

I am accustomed to get ClassCastExceptions from several of my test apps, 
but I always assumed these were due to Graphics2D not being properly 
implemented.

However, some testing reveals that GtkComponent.paintComponent() actually
casts to GdkGraphics, with GdkGraphics2D not a subclass of GdkGraphics.
Please tell me I am doing something stupid! I just won't believe that 
classpath could have run my apps for ages, if not for this particular way
of designing the type hierarchy. It seems that my custom component returns
a valid Graphics2D, but GtkComponent refuses to use that...

See attached testcase.
