Description

This code is suspicious:

    private PDStream configureOutputProfile (PDDocument doc, InputStream colorProfile) throws IOException {
        PDStream stream = new PDStream(doc,colorProfile, false); 
        stream.getStream().setFilters(COSName.FLATE_DECODE); 
        stream.getStream().setInt( COSName.LENGTH, stream.getByteArray().length ); 
        stream.getStream().setInt(COSName.N, 3); 
        stream.addCompression(); 
        return stream;
    }

N is hardcoded to 3, although it could be a CMYK profile.
