------------------------------
Summary: camel-as2: MDN multipart/report parsing issue with no
Content-Type
Key: CAMEL-22359
URL: https://issues.apache.org/jira/browse/CAMEL-22359
Project: Camel
Issue Type: Bug
Components: camel-as2
Affects Versions: 4.x
Reporter: msorce
We use Camel AS2 component to receive and send edifact messages to partners.
We're having issue parsing synchronous MDN from one of this partner.
The global Content-Type of the MDN is multipart/report.
The first part (the human readable text) has no Content-Type set.
This leads to a parsing bug whereas RFC 2045 (Section 5.2) specify that the
Content-Type can be omitted and should be considered as "text/plain;
charset=us-ascii".
