Rest Client Builder: 2.2.1 Doesn't send XML but does send JSON

[zaccak]

I tried using rest builder as such with success: def rest = new RestBuilder() def result = rest.post(url){ contentType "application/json" json "test" }

However when I change it to XML as below it doesn't send the XML payload and doesn't get picked up on my API: def rest = new RestBuilder() def result = rest.post(url){ contentType "application/xml" xml "test" }

I checked send xml via curl and it works fine: curl -i -X POST -H "Content-Type: application/xml" -d 'test' localhost:8090/TestMe/api
