Plugin keeps crashing my server

Hi,
Everytime i run my plugin is crashes my server. The goal of the program is every 2 minutes it swaps the players locations. The only idea i have why its crashing is that the timer is somehow messed up, but i can't seem to fix it.

Main:

Code:

package me.puppet172.death;

import org.bukkit.plugin.java.JavaPlugin;
import me.puppet172.death.commands.*;

public class Main extends JavaPlugin
{
  
    @Override
    public void onEnable()
    {
        new DeathCommand(this);
    }
}

Command File:

Code:

package me.puppet172.death.commands;

import org.bukkit.command.CommandExecutor;
import me.puppet172.death.Main;

import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import java.util.Timer;
import java.util.TimerTask;

public class DeathCommand implements CommandExecutor
{
@SuppressWarnings("unused")
private Main plugin;

private int pX= 0;
private int pY = 0;
private int pZ = 0;

private int p1X= 0;
private int p1Y = 0;
private int p1Z = 0;
private Player p;
private Player p1;
private int secondspassed= 0;
private Timer time = new Timer();
private TimerTask task = new TimerTask()
//double check timer is set up correctly
{

    @Override
    public void run()
    {
    secondspassed++;  
    Bukkit.broadcastMessage("Time: "+ secondspassed);
      
    }
  
};
public void start()
{
    time.scheduleAtFixedRate(task, 1000, 1000);
}
  
    public DeathCommand(Main plugin)
    {
        this.plugin = plugin;
        plugin.getCommand("death").setExecutor(this);
    }
    @Override
    public boolean onCommand(CommandSender send, Command cmd,String label, String[] args) {
    {
  
        send.sendMessage("The game has Started");
        p = (Player) send;
        p1= Bukkit.getPlayer(args[0]);
        start();
        while((p.getHealth()>0) && (p1.getHealth()>0))
        {
          
          
            if(secondspassed>110)
            {
                int time = 10;
                Bukkit.broadcastMessage("Time left: "+String.valueOf(time));
                time--;
            }
      
            while(secondspassed >= 120)
            {
              
              
              
                secondspassed = 0;
                location();
                p.teleport(new Location(p1.getWorld(),p1X,p1Y,p1Z));
                p1.teleport(new Location(p.getWorld(),pX,pY,pZ));
          
            }
        }
        if(p.getHealth()==0)
        {
            p.sendMessage("You Lost");
            p1.sendMessage("You Won");
        }else
        {
            p.sendMessage("You Won");
            p1.sendMessage("You Lost");
          
        }
      
        return true;
    }
  
}
    public void location()
    {
        pX = p.getLocation().getBlockX();
        pY = p.getLocation().getBlockY();
        pZ = p.getLocation().getBlockZ();
      
        p1X = p1.getLocation().getBlockX();
        p1Y = p1.getLocation().getBlockY();
        p1Z = p1.getLocation().getBlockZ();
      
    }
