Solved Java doesn't like me.

So, I get an NullPointerException, fair enough.
I change my code blablabla, and I get the same NPE, on the same line.
The difference is, that line contains a comment :l.

The problem, I seem to get errors only on line 35, doesn't matter what I put there.
When I use a debug message on my BlockBreakEvent, it doesn't even get fired.
Waaht?

BlockBreak

Code:java

 
private Strikerz m;
public BlockBreak(Strikerz instance){
m = instance;
}
 
public static HashMap<String, Integer> crux_health_black = new HashMap<String, Integer>();
public static HashMap<String, Integer> crux_health_white = new HashMap<String, Integer>();
 
int max_health_black = 20;
int max_health_white = 20;
 
@EventHandler
public void onBreak(BlockBreakEvent e){
    System.out.println("EVENT FIRED"); //Doesn't show.
    Block b = e.getBlock();
    Player p = e.getPlayer(); //Line 35
    if(p.getGameMode() != GameMode.CREATIVE){
        e.setCancelled(true);
    }
    if(!(m.ingame.isIngame(p))) return;

- Did you register.. ?
Yes. Else I wouldn't get an error when I mined something.

Post the Entire BlockBreak class so we can see what line 35 is.

 

Rmarmorstein Unica

It seems my OnDamage event also doesn't get fired.
There must be something wrong with the constructor

 

Your error description makes no sense, paste full class please.

 

The stacktrace you are getting is not from the code posted. Reasoning:
For one, the debug message you added does not print (as stated by yourself).
And there is no possible way an NPE could be thrown at that line, because that would imply that e points to null. Which it can't because the previous line goes through just fine.

My suggestion is that you recompile the project and make sure you upload the new version to your server and then restart the server and run the code again. Then post the new code and stacktrace here.

I will test in 20 minutes, i'll let you guys now (and post full code)

Update: Once ingame and I hit the 'crux' it works ? But I don't get the debug message.
EDIT: It kinda works, because when I break a random block the block doesn't drop anything.

Unica the plugin on the server is not the plugin you are pasting code of.

I am so sorry.
You can call me extremely stupid, because it was already working, I was saving my .jar file to a different folder rather than my actual testing server.

So I was testing the same .jar over again.
