There is a regression in ImageStream where the system property org.icepdf.core.ccittfax.jai=true is not correctly being applied.

The basic issue is as follows:

try {
    // corner case where a user may want to use JAI because of
    // speed or compatibility requirements.
    if (forceJaiccittfax) {
        throw new Throwable("Forcing CCITTFAX decode via JAI");
    }
    data = ccittFaxDecode(data, width, height);
    dataLength = data.length;
} catch (Throwable e) {
    // on a failure then fall back to JAI for a try. likely
    // will not happen.
    if (Tagger.tagging) {
        Tagger.tagImage("CCITTFaxDecode JAI");
    }
    decodedImage = CCITTFax.attemptDeriveBufferedImageFromBytes(
            this, library, entries, fill);
}

If the system property is true then we throw an exception and make the CCITTFax.attemptDeriveBufferedImageFromBytes() call but we never return the decodedImage an hens the problem.
