apple.awt.brushMetalLook support on OpenJDK7? - JNI solution?

[Tobias Bley]

Thanks Scott for that information. Maybe the CALayer implementation is the reason for the "bad redrawing behavior" when resizing the frame? Currently there is a very big quality gap between Apples AWT and the OpenJDK AWT implementation. flickering when resizing window, redrawing errors, bad perceived graphics performance...

Are there any open todos concerning AWT / graphics pipeline? Currently it's not possible to use OpenJDK 7 on Mac for a real commercial java application :(

Best regards,
Tobi
