In Weblogic 14c, when executing an MTOM SOAP Request, we are faced with the following exception:

This appears to be happening due to this line in org.apache.axis.attachments.MimeUtils:

multipart = new javax.mail.internet.MimeMultipart(
                        "related;type=\"application/xop+xml\"; start=\"<" + rootCID + ">\"; start-info=\"text/xml; charset=utf-8\"");

You can see that both start-info and charset are combined into a single header. The fix is to split the start-info and charset attributes to separate headers like this:

multipart = new javax.mail.internet.MimeMultipart(
                        "related;type=\"application/xop+xml\"; start=\"<" + rootCID + ">\"; start-info=\"text/xml\"; charset=\"utf-8\"");

After the code change, the issue is not reproducible.
