    Description

      I think the following describes a bug as I expect a Resteasy service to handle a java.lang.String return type successfully.

      I am using Resteasy in a ServiceMix 4.4.0 deployment. The Rest service is exposed via OSGi and consumed by another OSGi bundle. I have attached the sample project source code.

      ********************
      The following two method signatures when called via a Resteasy client will through an exception. See helloworld-integration-test/src/test/java/test/api/svc/HelloSvcTest.java
      ********************

      • The method signatures that throw an exception:
          @POST
    @Path( "/StandardGreeting" )
    @Consumes( { "application/json", "text/json" } )
    @Produces( { "application/json", "text/json" } )
    @GZIP
    @Override
    public Response getStandardGreeting( GreetingRequest request )
    {
        String value = "Hi " + request.getRecipientName()
                + "..."
                + " " + "How is it going?";

        return Response.ok().entity( new String( value ) ).build();
    }


          @POST
    @Path( "/SimpleHelloGreeting" )
    @Consumes( { "application/json", "text/json" } )
    @Produces( { "application/json", "text/json" } )
    @GZIP
    @Override
    public String getSimpleHelloGreeting( GreetingRequest request )
    {
        String value = "Hello " + request.getRecipientName() + "!!!";

        return new String( value );
    }
      • Will throw the following exception:
