Support Jackson based XML serialization in RestTemplate [SPR-12225]

[spring-projects-issues]

Sébastien Deleuze opened SPR-12225 and commented

Since Spring 4.1.x now supports Jackson based XML serialization, RestTemplate should create a MappingJackson2XmlHttpMessageConverter instead of a Jaxb2RootElementHttpMessageConverter when Jackson XML extension is detected on the classpath, like WebMvcConfigurationSupport do.
