Spring JSON causes problems when the Spring framework is upgraded from 3.0.2 to 3.2.0

Hi Kent,

Thanks for your response...I had tried previously with produces ="application/json" and it didnt work. Also now i tried with

	@RequestMapping(method = RequestMethod.GET, value = { WebApplicationConstants.SWITCH_USER_URL },produces = "application/json;charset=UTF-8")

Still am getting 406. Also I would like to tell you one more observation that we have made. The moment when I change the return type from an Object to a String, it works....

Existing:

public @ResponseBody
CustomResponse switchUser(
@RequestParam(WebApplicationConstants.SESSION_TOKE N) String gsxSessionToken,
@RequestParam(WebApplicationConstants.SWITCH_FLAG) String switchFlag,
HttpServletRequest request,
HttpServletResponse response,

Return Type:
return new CustomResponse(jsonObject.toString());

New:
)
public @ResponseBody
String switchUser(
@RequestParam(WebApplicationConstants.SESSION_TOKE N) String gsxSessionToken,
@RequestParam(WebApplicationConstants.SWITCH_FLAG) String switchFlag,
HttpServletRequest request,
HttpServletResponse response,


Return Type:
return (jsonObject.toString());

But this involves changes across application and is not a recommended solution that we are looking for. Could you please let us know how we can tackle this error?
