I am converting a buffered image from CS_sRGB color space to CS_CIEXYZ color space and then writing the color converted image in different formats using ImageIO. I am loading back the images written and showing it on a frame. JPEG ImageReader throws an exception when trying to read the image written by ImageWriter, when the input buffered image is one of the following types -

1. TYPE_INT_ARGB
2. TYPE_INT_ARGB_PRE
3. TYPE_4BYTE_ABGR
4. TYPE_4BYTE_ABGR_PRE
5. TYPE_BYTE_BINARY
6. TYPE_BYTE_INDEXED

Here is the exception:
javax.imageio.IIOException: Unsupported Image Type

This is thrown when writing/reading the image color converted from CS_sRGB to CS_CIEXYZ.
I reproduced it on Ubuntu 7.10 with openjdk-6.

I have attached the sample test and the image herewith.
