RXTX mismatch version mismatch

I am writing a program on Processing V1.5.1, to receive serial data on Raspberrypi from windows machine. I am struggling in receiving serial data on executing program and got this message(below). I am not sure it is error or not, but I am not getting my desire result. I am using Tx and Rx (GPIO 14 and 15) for serial communication and when I check it on Minicom, it is working fine. Can you please guide me on how do I resolve this issue?

CODING =====
import processing.serial.*;

Serial myPort;
String input;

void setup()  {

  myPort = new Serial(this, "/dev/ttyAMA0", 9600);
  println(Serial.list());
  myPort.bufferUntil('\n');
}

void serialEvent(Serial port) {

input = port.readString();
println (input);
}

ERROR ====
