Subj : Rhino - Getting a list of functions

I have been racking my brain for the last couple of days trying to 
figure out how to solve this problem:

Given a JavaScript source file, I'm trying to get Rhino to output all 
the functions defined in that file, including nested functions (such as 
those in JS Classes) with their line number.  Using the code below, I am 
able to get the name of all the top-level functions and their line 
number, however, class functions only return the line number and the 
name is blank.  What am I doing wrong?  The code I'm using is below:

###############
##### JAVA #####
###############

public static void main(String[] args){

    // Read JS file into source variable
    .....
   
    Script script = cx.compileString(source, path, 1, null);
    findElements(Context.getDebuggableView(script));
}

public static void findElements(DebuggableScript debug){
   
    int[] lines;
    for(int i = 0; i < debug.getFunctionCount(); i++){
       
        // Get linenumber
        lines = debug.getFunction(i).getLineNumbers();
        int line = -1;
        if(lines.length > 0){
            line = lines[0];
            for(int l = 0; l < lines.length; l++){
                if(lines[l] < line){
                    line = lines[l];
                }
            }
        }
       
        // Print
        System.out.print("\n["+ line +"] ");
        System.out.print(debug.getFunction(i).getFunctionName() +"\n");
       
        // Get Sub-Functions
        findElements(debug.getFunction(i));
    }
}

    this.propOne = false;
    this.propTwo = "hello";
    this.propThree = "world";

    }
   
    this.methodFuncTwo = function(){
   
    }

function helloWorld(){
