So, I'm working on a program that allows you to import animations in the form of JSON files into Minecraft, and, when working on a completely different part of the program, my import code stopped working.

I'm using eclipse, and this is how my import code looks:

package com.github.sam54123.mc_animation.utils;



import java.io.InputStream;



public class FileHandle 

{

    public static InputStream inputStreamFromFile(String path)

    {

        try

        {

            InputStream inputStream = FileHandle.class.getResourceAsStream(path);

            return inputStream;

        }

        catch(Exception e)

        {

            e.printStackTrace();

        }



        return null;



    }

}

new file

package com.github.sam54123.mc_animation.utils;



import java.io.File;

import java.io.InputStream;

import java.util.Scanner;



import org.json.JSONObject;



public class JSONUtils 

{

    public static String getJSONStringFromFile(String path)

    {

        // Open file

        Scanner scanner;

        try 

        {

            InputStream in = FileHandle.inputStreamFromFile(path);

            scanner = new Scanner(in);

            // Get JSON as string without spaces or newlines

            String json = scanner.useDelimiter("\Z").next();



            // Close file

            scanner.close();



            return json;



        }

        catch(Exception e)

        {

            System.out.println(e.getStackTrace());

            return null;

        }





    }



    public static JSONObject getJSONObjectFromFile(String path)

    {

        File file = new File(path);

        if (!file.exists())

        {

            System.out.println("Invalid Path");

            return null;

        }



        String string = getJSONStringFromFile(path);

        return new JSONObject(string);



    }







}

And I proceed to do some more fancy pampering of the file later on. This used to work reliably, until I made this in a completely different and un-related class:

String command = getCommand(object);



if (command != null && command.length() > 0)

{

    commands.add(new AnimCommand(command, i));

}

And then it started throwing this error:

   [Ljava.lang.StackTraceElement;@7852e922

Exception in thread "main" java.lang.NullPointerException

    at java.io.StringReader.<init>(Unknown Source)

    at org.json.JSONTokener.<init>(JSONTokener.java:94)

    at com.github.sam54123.mc_animation.testing.Tester.main(Tester.java:13)

I've double checked that the file hasn't changed, and I tried deleting that section of code, restarting Eclipse, the whole deal, and nothing seems to fix it. The code is even able to recognize that the file is valid using the File class, but nothing seems to change. Does anyone have some insight on how this might be fixed? Here is the rest of my code: https://github.com/Sam54123/mc-animation/

EDIT

Okay, I've just done some more debugging, and it looks like it's the

return new JSONObject(string);

on line 47 of the second file that's crashing. No idea why, as the risky stuff of reading a file off disk is okay.

EDIT 2
It looks looks like it's failing because

InputStream in = FileHandle.inputStreamFromFile(path);

is returning null, which makes sense because of the try catch statement

InputStream inputStream = FileHandle.class.getResourceAsStream(path);

is in. Why that's failing beats me though, because the validity of the file is verified elsewhere in the code. It also used to work, and I haven't changed anything about the layout of the files.

EDIT 3
Interesting, a couple System.out.printlns reveal the catch is not actually getting activated, and therefore getResourceAsStream() must actually be returning null. I've confirmed this by printing it out before I return it.
