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.

> Affects Versions: 3.1.2
> Reporter: Balarami Reddy
> Assignee: Sergey Beryozkin
>
> 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();
> }
