Description

If you define two or more JaxbContexts in mule xml config and try to use autotransformer to unmarshall the xml to java object, the transformation fails. There's also no way to tell the auto-transformer to what jaxbContext to use.

I forgot to mention that the workaround for this is to use: jaxb-xml-to-object-transformer but as far as I know the auto-transformer are used in endpoints to transform the request and response messages, so this also affects the use of endpoints.

I get the same error and I'm only using jaxb-xml-to-object-transformer, although I'm not using returnClass because the service I'm connecting to returns 1 of 2 possible classes, which I have no control over.
