Camel-CXF endpoint using CXF_MESSAGE dataformat with MTOM

Issue

• We'd like to use Camel-CXF with CXF_MESSAGE dataformat. We're using this format because we want to access the raw soap message whilst leveraging CXF interceptors.

• When using CXF_MESSAGE mode, the route receives an instance of SOAPMessage. We then convert it into a String using convertBodyTo(String.class), so we can manipulate the request using XSLT.

This works fine when the message isn't using MTOM but does not work otherwise.
