How to prevent JAX.RS ExceptionMapper including the stacktrace - exception

Question

I have the following code in my JAX.RS ExceptionMapper:
#Override
public Response toResponse(ResponseStatusCodeException ex) {
ResponseStatusCode newEx = new ResponseStatusCode(ex);
return Response.status(ex.getStatus()).entity(newEx).type(MediaType.APPLICATION_JSON).build();
}
This generates a JSON response that includes a full exception stack trace starting in the Response.status() line.
How can I make the ExceptionMapper just to return the JSON encoded properties for the newEx class. I have even tried making ResponseStatusCode a POJO not extending Exception but the stack trace is always included in the response.
I am using Websphere Liberty profile 8.5.5.8.
Thanks
Edited: Let me add the JSON generated:

}
And the POJO:
package com.servengine.ws.rs;
public class ResponseStatusCode extends Exception {
private static final long serialVersionUID = 1L;
private int status;
private String message, username, code;
public ResponseStatusCode(ResponseStatusCodeException exception) {
this.message = exception.getMessage();
this.username = exception.getUsername();
this.code = exception.getCode();
this.status = exception.getStatus();
}
public int getStatus() {
return status;
}
public void setStatus(int status) {
this.status = status;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}

Answer 1

If the class to be marshalled to JSON extends Exception, a stack trace will be included. I changed it to Serializable, which I had not done yet, and no stack trace is included.
Many thanks to #peeskillet for his replies.

Answer 2

If you are using jackson to marshal POJO to JSON, you may try this:
#JsonIgnoreProperties(value = "stackTrace")
public class ResponseStatusCode extends Exception
