POST contentType always shows text/plain even though content is XML

Question

I am working on a RESTful application using Apache Karaf, OSGi, JPA, JAX-RS & JAX-B.

While doing the POST operation I am facing a issue where in I am always getting the contentType as text/plain in the logs while I am sending APPLICATION_XML.

Here are the logs below:

I tried other operations such as GET, DELETE which are able to call the subsequent function correctly but I can't seem to send the POST and it shows this issue every time.

Can anyone plz help me here?

From the comments and doing a bit more research on PostMan's development.

The simple extension version does not currently default the Content-Type of the request based on the dropdown in associated to the raw post body header. You need to instead the Content-Type explicitly using a header explicitly.

Looking on Postman's Github, it seems this is not a new bug. Digging through issues, it seems that there is also a Packaged App version of Postman which behaves properly, and gives you distinct options for XML (application/xml) and XML (text/xml) even.
