Subject [jira] [Commented] (AXIOM-467) Cannot read "quoted-printable" encoded data from MIME part
Date Sat, 16 May 2015 00:59:00 GMT

    [ https://issues.apache.org/jira/browse/AXIOM-467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14546460#comment-14546460
] 

Andreas Veithen commented on AXIOM-467:
---------------------------------------

That's not what I would call a real world example. It's a specially crafted to trigger the
issue. In fact, Axiom <= 1.2.12 rejects messages that use CR instead of CRLF in the MIME
headers. To trigger a backward incompatibility issue, the message therefore needs to use CRLF
in the headers and CR in the content. It's not impossible that there are real world systems
that would produce such (non conforming) messages, but I think it's very unlikely, in particular
considering that using quoted-printable encoding in SwA or MTOM messages is already very rare.

> Processing "quoted-printable" encoded data in the axiom v.1.2.13 seems to be backward
incompatible as it was in the axiom. 1.2.7.
> I provided one and the same test case which illustrates how the test is working in the
axiom 1.2.7 but not in 1.2.13.
> In the axiom 1.2.13 I got the following exception:

> The root cause of this exception is that AXIOM forces usage of the STRICT mode of MIME4J
for decoding found in org.apache.axiom.attachments.MIMEMessage class
>     MimeConfig config = new MimeConfig();
>     config.setStrictParsing(true);
> The default behavior MIME4J is SILENT(relaxed)  mode, if the strict parsing is not enforced
that the test will pass successfully.
