I am creating a buffered image from the default GraphicsConfiguration by calling GC.createCompatibleImage(). I am rendering some 2D shapes into the buffered image and trying to write this buffered image to a file using GIF Writer, using the default Image Metadata. GIFWriter.writeToSequence() throws a NullPointerException as follows:

java.lang.NullPointerException
at com.sun.imageio.plugins.common.PaletteBuilder.findPaletteEntry(PaletteBuilder.java:310)
at com.sun.imageio.plugins.common.PaletteBuilder.getIndexColorModel(PaletteBuilder.java:296)

at GIFCreateImageTest.createAnimatedImage(GIFCreateImageTest.java:142)
at GIFCreateImageTest.<init>(GIFCreateImageTest.java:65)
at GIFCreateImageTest.main(GIFCreateImageTest.java:180)

This is reproducible on all platforms with Mustang-b43.

I have attached a sample test. Execute the sample test. YOu would see the above exception on the console.
