Solved NullPointer Exception?

I'm getting a NullPointer exception in onEnable when I try to

try (Reader reader = new InputStreamReader(nCore.class.getResourceAsStream(getDataFolder().toString() + File.separatorChar + "testjson" + ".json"), "UTF-8")) {

nCore is the class extending JavaPlugin, and yes, I have an existing file called "testjson.json" inside plugins/ncore

Code:

[19:11:13 ERROR]: Error occurred while enabling nCore v1.0-SNAPSHOT (Is it up to
date?)
java.lang.NullPointerException

Line 55 is

PHP:

try (Reader reader = new InputStreamReader(nCore.class.getResourceAsStream(getDataFolder().toString() + File.separatorChar + "testjson" + ".json"), "UTF-8")) {

 

@DoggyCode™
If the file null? Is the resource stream null?

 

@DoggyCode™
Why are you trying to get the InputStream at runtime? Do you not have another way to access a reference to the stream?

Well, instead of using nCore.class.getResourceAsStream(getDataFolder().toString() + File.separatorChar + "testjson" + ".json", I switched to just new File(...) and it worked.
