Description

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:
org.apache.axiom.om.OMException: org.apache.axiom.ext.io.StreamCopyException: Error reading from source

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.
