convertTo7Bit and Java bug ID 4403733

[li...@mitm.nl]

Hi,

 

It seems that convertTo7Bit is also plagued by Java bug 4403733 (see
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4403733). If a message is
multipart all individual parts are converted to 7bit. The problem though is
that because of bug  4403733 the changed parts are not persistent. A
possible workaround, taken from the bug report, is to add a setContent

 

 

    private void convertTo7Bit(MimePart part) throws MessagingException,
IOException {
        if (part.isMimeType("multipart/*")) {
            MimeMultipart parts = (MimeMultipart) part.getContent();
            int count = parts.getCount();
            for (int i = 0; i < count; i++) {
                convertTo7Bit((MimePart)parts.getBodyPart(i));
            }
            part.setContent(parts);
<============================================ setContent added
        } else {
            if (part.isMimeType("text/*")) {
                part.setHeader("Content-Transfer-Encoding",
"quoted-printable");
                part.addHeader("X-MIME-Autoconverted", "from 8bit to
quoted-printable by "+getMailetContext().getServerInfo());
            } else {
                // if the part doesn't contain text it will be base64
encoded.
                part.setHeader("Content-Transfer-Encoding", "base64");
                part.addHeader("X-MIME-Autoconverted", "from 8bit to base64
by "+getMailetContext().getServerInfo());
            }
        }
    }

 

Is my observation correct?
