convertTo7Bit and Java bug ID 4403733

[mailing lists <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?

You may also be interested in:
http://issues.apache.org/jira/browse/JAMES-52
and
http://archives.java.sun.com/cgi-bin/wa?A2=ind0605&L=javamail-interest&F=&S=&P=3478

PS: theoretically the bug 4403733 has been closed in Javamail 1.4 and 
the setContent should not be needed anymore, but you can read in the 
previous link that this is not totally true.
