Resteasy client Error "The request sent by the client was syntactically incorrect" when using Hebrew

[daphna deutsch]

I have an apache server with rest APIs accepting Json object and produce Json object.
testing the sever using Chrome advanced rest client show no problems.

I then tried to create a jave client, using org.jboss.resteasy:

public T sendPostRequest(String url, T input) throws Exception {
		ClientRequest request = getNewClientRequest(url);

		ObjectMapper om = new ObjectMapper();
		final String body = om.writeValueAsString(input);

		request.body(MediaType.APPLICATION_JSON, body);
		final ClientResponse<String> responseObj = request.post(String.class);
		validateResponseString(url, responseObj);
		String responseString = responseObj.getEntity(String.class);
		responseObj.releaseConnection();

		return getObjectResponse(responseString, getElementType());
	}

When trying to use this method to send object containing Hebrew characters such as the following JSON:

{
  "id": 652,
  "firstName": "דפנה"
}

I'm getting the error code HTTP Status 400, error message: The request sent by the client was syntactically incorrect.
I never reach the server.

Sending the same object using Chrome advanced rest client works fine.
Sending it with English name also works.

The API:

@RequestMapping(value = "/insert", method = RequestMethod.POST, produces = { MediaType.APPLICATION_JSON }, consumes = "application/json;charset=UTF-8")
	public Student insertStudent(@RequestBody @Validated Student student, BindingResult bindingResult) throws GalCenterException {
		if (bindingResult.hasErrors()) {
			throw new GalCenterException(bindingResult.getAllErrors());
		}
		return studentService.insert(student);
	}

thanks!

Are you setting the Character Set while using RESTEasy based Java Client?

I'm not sure where to set it?
I tried to add in the request header but it didn't help.
