I have a buffered image which I am filtering through ColorConvertOp with source color space set to sRGB and dest color space set to CS_PYCC. I am trying to save the output image to a file using JPEG Writer and JPEG Writer throws the following exception -

javax.imageio.IIOException: Bogus input colorspace
at com.sun.imageio.plugins.jpeg.JPEGImageWriter.writeImage(Native Method)
at com.sun.imageio.plugins.jpeg.JPEGImageWriter.write(JPEGImageWriter.java:996)

JPEG Writer throws the above exception for the following buffered image types when the destination color space is CS_PYCC (whatever may be the source color space) -
TYPE_BYTE_GRAY
TYPE_INT_RGB
TYPE_INT_BGR
TYPE_3BYTE_BGR
TYPE_USHORT_555_RGB
TYPE_USHORT_565_RGB

JPEG Writer throws the above exception for the following buffered image types when the dest color space is CS_GRAY (regardless of src color space) -
TYPE_INT_ARGB
TYPE_INT_ARGB_PRE
TYPE_4BYTE_ABGR
TYPE_4BYTE_ABGR_PRE
TYPE_BYTE_BINARY
TYPE_BYTE_INDEXED

This is reproducible on win32 as well as sol10 atleast since 1.5+.

I have attached a sample test which reproduces the above issue for TYPE_INT_RGB with CS_PYCC color space. Run the attached test and you will get the exception on the console.
