        FileInputStream fis = new FileInputStream(new File("veraPDF test suite 6-1-12-t02-fail-a.icc"));
        ICC_Profile instance = ICC_Profile.getInstance(fis);
        fis.close();
        File iccFile;
        FileInputStream fis2 = new FileInputStream(iccFile = new File("veraPDF test suite 6-1-12-t02-fail-a.icc"));
        byte[] iccBuf = new byte[(int) iccFile.length()];
        fis2.read(iccBuf);
        ICC_Profile instance2 = ICC_Profile.getInstance(iccBuf); // exception
        fis2.close();
