javax.ws.rs.ProcessingException: RESTEASY003145: Unable to find a MessageBodyReader of content-type application/xml and type interface java.util.List

I have implemented a simple rest endpoint that returns a Response that contains a

List<String>

The client is implemented with jaxrs 2.0 and with resteasy as impl since I am using wildfly in my project. When I fetch the results I keep taking the following exception

javax.ws.rs.ProcessingException: RESTEASY003145: Unable to find a MessageBodyReader of content-type application/xml and type interface java.util.List

at org.jboss.resteasy.core.interception.ClientReaderInterceptorContext.throwReaderNotFound(ClientReaderInterceptorContext.java:42)
at org.jboss.resteasy.core.interception.AbstractReaderInterceptorContext.getReader(AbstractReaderInterceptorContext.java:80)

at org.jboss.resteasy.client.jaxrs.internal.ClientResponse.readEntity(ClientResponse.java:251)
at org.jboss.resteasy.specimpl.BuiltResponse.readEntity(BuiltResponse.java:245)

Here is the code from the client that produces the error. If I request JSON it works fine but with xml I get the above exception.

Invocation.Builder request = rTarget.path("/containers/instances/{id}/kbase/{kbaseName}").resolveTemplate("id", containerAlias).resolveTemplate("kbaseName", getKbase()).
            request(MediaType.APPLICATION_XML).accept(MediaType.APPLICATION_XML);

    return request.get().readEntity(new GenericType<List<String>>(){});

and here are my depedencies so far
