How to upload an arduino sketch from java / processing?

I'm trying to upload a hex file from Java/Processing but running into some issues. Here is my code so far, based on the Arduino IDE's upload verbose output:

void setup(){
    //C:\Program Files (x86)\Arduino/hardware/tools/avr/bin/avrdude -CC:\Program Files (x86)\Arduino/hardware/tools/avr/etc/avrdude.conf -v -v -v -v -patmega328p -carduino -PCOM96 -b115200 -D -Uflash:w:C:\Users\HM\AppData\Local\Temp\build5909267154049588263.tmp/sketch_aug13a.cpp.hex:i
    String ArduinoPath = "C:\\Program Files (x86)\\Arduino";
    String hexPath = "C:\\Users\\HM\\AppData\\Local\\Temp\\build1023547366107161384.tmp/sketch_aug13a.cpp.hex";
    String port = "COM96";
    runCommand(new String[]{ArduinoPath+"/hardware/tools/avr/bin/avrdude", "-C"+ArduinoPath+"/hardware/tools/avr/etc/avrdude.conf","-v","-v","-v","-v","-patmega328p","-carduino","-P"+port,"-b115200","-D","-Uflash:w:"+hexPath+":i"});
  }
  void runCommand(String[] cmd){

    String s = null;
    
    try {
    
      Process p = Runtime.getRuntime().exec(cmd);
      BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
      BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
    
      // read the output from the command
      System.out.println("command out:\n");
      while ( (s = stdInput.readLine ()) != null) System.out.println(s);
      System.out.println("errors (if any):\n");
      while ( (s = stdError.readLine ()) != null) System.out.println(s);
      
    }catch (IOException e) {
      System.out.println("something went wrong: \n");
      e.printStackTrace();
    }
  
  }

If I run this from command line it uploads without any issues, but from the code above I always get this output:
