My console keeps getting spammed with these two things:
(When a player is moving)

Code:

[SEVERE] Could not pass PlayerMoveEvent to WarHexagon vv1.0

(When a player interacts with things)

Code:

[SEVERE] Could not pass PlayerInteractEvent to WarHexagon vv1.0

There is no stacktrace, it's just those messages spammed over and over again.

Here is my PlayerMoveEvent and PlayerInteractEvent:

PlayerMoveEvent (open) PlayerMoveEvent (close)

Code:java

@EventHandler
    public void onPlayerMove(PlayerMoveEvent e) {
        if (!Join.arenaSigns.get(game).contains(e.getPlayer().getName())) return;
        if (override.contains(e.getPlayer().getName())) return;
        if (stun.contains(e.getPlayer().getName())) {
            e.setCancelled(true);
        }
        Block damage = e.getPlayer().getWorld().getBlockAt(e.getTo()).getRelative(0, 0, 0);
        if (damage.getType() == Material.FIRE) {
            double health = e.getPlayer().getHealth();
            e.getPlayer().setHealth(health-.5);
            damage.setType(Material.AIR);
        }
    }

PlayerInteractEvent (open) PlayerInteractEvent (close)

Code:java

@EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
        Player p = e.getPlayer();
 
        if (p.getItemInHand().getType() == Material.PAPER) {

I think it may be due to my Hashmap, arenaSigns. I removed the arenaSigns code in my playermoveevent, and the spam stopped.

Also, I did some testing and it seems that when to "arenaSigns.get(line).add(p.getName());" that's where the code stops running.

Squid_Boss Can you post the full stack traces, They will be located in your server log

 

DailyLove I looked at the latest in my server logs, and there are no stacktraces, it's just a continuous spam of those messages (first post).

 

Could the issue be related to the fact that when I call my hashmap, "line" and then I add a string to it, instead of a string list ?

After looking over CubieX 's post (found here), I have ran across another error:
Whenever I try to put the player into the hashmap's ArrayList like this

Code:java

myHashMap.put(arenaName, myHashMap.get(arenaName).add(playerName));

I get an error under "put", saying that "the method put(String, ArrayList<String>) is not applicable for the arguements (String, boolean) because "add(playerName)" is returning as a boolean....is there a work around for this? Here is my code:

Code:java

if (!arenaPlayers.containsKey(line)) {
      arenaPlayers.put(line, new ArrayList<String>());
}
if (!arenaPlayers.get(line).contains(p.getName())) {
       arenaPlayers.put(line, arenaPlayers.get(line).add(p.getName()));
}

When you use the add method for Lists, it doesn't return the list, instead it returns a boolean that tells if it suceeded.
Try doing:

Code:

if (!arenaPlayers.get(line).contains(p.getName())) {
      ArrayList<String> list = arenaPlayers.get(line);
      list.add(p.getName())
      arenaPlayers.put(line, list);
}
