[jira] [Reopened] (CXF-6902) Problem with resource that returns Object with CXF version == 3.1.2

Balarami Reddy reopened CXF-6902:
---------------------------------

Hi Sergey,

I debugged the code of 2.7.3 to see how it was working and which provider could convert integer to JSON and it was found to be PrimitiveTextProvider.

I also observed one change from 2.7.3 to 3.1.2 in PrimitiveTextProvider supports method.

In 3.1.2, an extra condition is added mt.isCompatible(MediaType.TEXT_PLAIN_TYPE) which means this provider is supported only if the method produced type is compatible with TEXT_PLAIN_TYPE and it broke backward compatibility where it used to work for APPLICATION_JSON also.

Please advice us on what best can be done.

Thanks
Balaram.

> Hello,
> We have recently migrated from 2.7 to 3.1.2 and we see a behaviour change in CXF which blocked us from making progress.
> The sample code below gives "No message body writer has been found for response class Integer" which used to work perfect in CXF 2.7
> This is just sample code only. We have in our product several rest calls which return integer/long/Object etc based on some calculations.
> 	@GET
> 	@Produces(MediaType.APPLICATION_JSON)
> 	@Path("/getinteger")
> 	public Response getInteger() {
> 		return Response.ok(4).build();
> 	}
