[Bug swing/24099] New: GdkGraphics2D.copyArea() needs to be implemented

[hendrich at informatik dot uni-hamburg dot de]

The recent changes to the Swing repainting mechanism rely on
Graphics.copyArea(), but that method is not implemented in GdkGraphics2D.
The overall effect is that I cannot any longer run my test applications
with Graphics2D enabled (-Dgnu.java.awt.peer.gtk.Graphics=Graphics2D), 
due to instant UOEs on every repaint:


Exception during event dispatch:
