Ok Alessandruino - DualPwm should be worky. 
 

This is the testing I did ...

Runtime.start("webgui", "WebGui");

arduino = (Arduino)Runtime.start("arduino", "Arduino");

motor01 = (Motor)Runtime.start("motor01", "Motor");

motor01.setPwmPins(3, 4);

motor01.attach(arduino);

 

arduino.connect("COM5"); 

 

motor01.move(0.3);

motor01.move(0.1);

motor01.move(1.0);

motor01.move(5.0);

 

motor01.move(-0.1);

motor01.move(-0.2);

motor01.move(0.0);

motor01.stop();
