Hi,

I have a Java application which does lots of image processing and on OS X I get literally thousands of messages of the form:

ERROR: CGContextGetPixelAccess returns NULL in syncToJavaPixels!

output on the console. It's hard to find out exactly what triggers this, but one thing that often does is calling drawImage in a JComponent's paintComponent method with a custom Composite, although other things do as well. Does anyone have any ideas as to how to stop this happening?

Thanks,

Jerry
