> We use Apache Camel AS2 libraries in our application to receive and process AS2 messages.
> Currently, we tracked down an issue where a client message's signature fails to be validated.
> It turns out that the message content contains CRLF line endings in the mime part body, while the original message has LF only.
> We were able to verify that replacement LF->CRLF is carried out in CanonicalOutputStream, which is used in AS2 implementation to marshal the signed entity in SigningUtils::isValid into a byte array.
