Hi,
I am in the middle of migrating Apache Syncope trunk from CXF 2.7.8 to
3.0.0-milestone1.
By following [1] and [2] it has been quite straightforward to make
almost everything working, with some exceptions: it seems that
proxy-based clients are not able any more to handle primitive type results.
For example, when calling UserService#count [3], the proxy-based client
raises (Content-Type XML or JSON does not make any difference):
[main] ERROR org.apache.cxf.jaxrs.utils.JAXRSUtils - Problem with
reading the data, class int, ContentType: application/xml;charset=UTF-8.
Exception in thread "main"
javax.ws.rs.client.ResponseProcessingException: Problem with reading the
data, class int, ContentType: application/xml;charset=UTF-8.

Am I missing something?
It actually exposes the fact the existing issue, I've had a test working
with a primitive value but for whatever reasons (copy & paste most
likely) HTTP Client was used to read String and test it for "true" as
apposed to using WebClient or Proxy to cast it to primitive 'boolean'.
I've refactored the client code a lot in 3.0.0 to consolidate all the
reading of responses in Response.readEntity and it will work with CXF
webClient, Proxy, Response itself and new Client API, but the lack of
tests got the introduced proxy related issue missed,
I've just fixed it, thanks
Sergey
TIA
