Well, if this is not allowed, maybe iText should throw an exception on writing
if someone is trying to do that?

As I can see in the code, iText does that for all images, which are tagged with
profile (code from com.itextpdf.text.pdf.PdfWriter:
if (image.hasICCProfile()) {
PdfICCBased icc = new PdfICCBased(image.getICCProfile(),
image.getCompressionLevel());
PdfIndirectReference iccRef = add(icc);
PdfArray iccArray = new PdfArray();
iccArray.add(PdfName.ICCBASED);
iccArray.add(iccRef);
PdfArray colorspace = i.getAsArray(PdfName.COLORSPACE);
if (colorspace != null) {
if (colorspace.size() > 1 &&
PdfName.INDEXED.equals(colorspace.getPdfObject(0)))
colorspace.set(1, iccArray);
else
i.put(PdfName.COLORSPACE, iccArray);
}
else
i.put(PdfName.COLORSPACE, iccArray);
}
)

What should be performed in this case? What does Acrobat Pro do when you're
trying to insert jpeg image with CMYK profile into the pdf?
