XmlDataContentHandler is not compatible with JavaMail

[Tomas-Kraus]

The MimeCodec class installs some JAF DataContentHandlers that override the default DataContentHandlers included with JavaMail. Unfortunately, the JAX-WS text/xml handler is not compatible with the JavaMail version.

First, the MIME type comparison is not case insensitive.

Second, it's returning a StreamSource as the preferred type from getContent instead of String.

Third, even if you ask for a String explicitly from getTransferData, it still returns a StreamSource.

The other DataContentHandlers should be checked for similar problems.

Affected Versions

[2.2.8]
