You should always debug your program in some IDE. For Pogamut the best choice is obviously NetBeans. If you would do that, you would receive null pointer exception at Main.java at line 126. :-) You have forgotten to initialize your path2goal variable.

After the definition, which is:

public  ArrayList path2goal = null;

You haven't actually created any ArrayList, so what you have is an empty pointer, which of course, cannot be assigned to with path2goal.add(0, nearestNavPoint); 

The solution: 
public  ArrayList path2goal = new ArrayList ();

In Java you work with pointers to objects - don't forget to create those object. If you are new to Java, there are plenty of tutorials on the web.

Best,
