Hi,

I used some "old" osc processing code and opened it in the new version of processing, but when I ran the code,  it gave me an error message pointing at         oscP5 = new OscP5(
               this,
               host,
               sendToPort,
               receiveAtPort,
               oscP5event
               );

The message: Null pointer exception

I wonder if a mac intell makes a difference here, because I can run this processing code fine in earlier versions of processing ...

Here's the entire code:

import oscP5.*;

import processing.opengl.*;

float c1,  c2,  c3,  c4, c5,  c6,  c7,  c8, b1, b2, b3,  b4, b5,  b6;


OscP5 oscP5;
int receiveAtPort;
int sendToPort;
String host;
String oscP5event;

void initOsc() {
       receiveAtPort = 7005;
       sendToPort = 7006;
       host = "127.0.0.1"; // 127.0.0.1 means talk to your own computer - it is a syntax 192.168.0.6
       oscP5event = "oscEvent";
       oscP5 = new OscP5(
               this,
               host,
               sendToPort,
               receiveAtPort,
               oscP5event
               );
}


void oscEvent(OscIn oscIn) {
       //println("received a message ... forwarding to analyseMessage(OscIn)");
       c1 = oscIn.getFloat(0); // an index inside a message
       c2 = oscIn.getFloat(1);
       c3 = oscIn.getFloat(2);
       c4 = oscIn.getFloat(3);
       c5 = oscIn.getFloat(4);
       c6 = oscIn.getFloat(5);
       c7 = oscIn.getFloat(6);

       b3 = oscIn.getFloat(10);
       b4 = oscIn.getFloat(11);
       b5 = oscIn.getFloat(12);
       b6 = oscIn.getFloat(13);
//if (b1 == 1.0) {
