Subject [jira] [Commented] (AXIOM-467) Cannot read "quoted-printable" encoded data from MIME part
Date Mon, 11 May 2015 07:04:00 GMT

    [ https://issues.apache.org/jira/browse/AXIOM-467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14537669#comment-14537669
] 

Detelin Hadzhiev commented on AXIOM-467:
----------------------------------------

No I don't have another example, but the provided one is a real XML document encoded as "quoted-printable"
content. 
I'm pretty sure the issue could be reproduced with any larger encoded XML document.
Using relax mode is necessary otherwise axiom will not be backward compatible for documents
that have small deviations form the MIME spec.

> 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.
