Projectiles and explosions affecting scheduler bug

So I have a anti combat log but however projectiles and explosions make the scheduler buggy. Why is that?

The timer gets decremented wrong. For example sometimes it counts down too fast or the numbers are out of order counting from 10 only when the player gets attacked by a projectile or an explosion.

Code:

int time = 10;
public ArrayList<String> combatlogged = new ArrayList<>();
    @EventHandler
    public void onDamage (EntityDamageByEntityEvent e) {
        Entity attacked = e.getEntity();
        Entity attacker = e.getDamager();
        if (e.getEntity() instanceof Entity && e.getDamager() instanceof Entity) {
            if(!combatlogged.contains(attacked.getName()) || (!combatlogged.contains(attacker.getName()))) {
            combatlogged.add(attacked.getName());
            combatlogged.add(attacker.getName());
            attacker.sendMessage(ChatColor.GOLD + "You're now in Combat!");
            attacked.sendMessage(ChatColor.GOLD + "You're now in Combat!");
      
            new BukkitRunnable() {
                 @Override
                    public void run()
                    {
                     if ((combatlogged.contains(attacker.getName())) && (combatlogged.contains(attacked.getName()))) {
                        if (time == 0)
                        {
                               combatlogged.remove(attacker.getName());
                               combatlogged.remove(attacked.getName());
                               attacker.sendMessage(ChatColor.GREEN + "You can now log out safely.");
                               attacked.sendMessage(ChatColor.GREEN + "You can now log out safely.");
                               time = 10;
                               this.cancel();
                               return;
                        }
                        attacked.sendMessage(time + " second(s) remains!");
                        attacker.sendMessage(time + " second(s) remains!");         
                    time--;                           
                    }
                    }         
            }.runTaskTimer(Main.getInstance(), 20L, 20L);   
        } else {
            attacker.sendMessage("added 10 seconds to combat time");
            attacked.sendMessage("added 10 seconds to combat time");
            time = 10;
        }
        }
    }

 

Edit:

The timer gets decremented wrong. For example sometimes it counts down too fast or the numbers are out of order counting from 10 only when the player gets attacked by a projectile or an explosion.

You can test the code if you want.

 

How do I make it player specific?

 

How would I add the timer into the hashmap?

For example decrementing the int inside the hashmap for the timer.

 

How do you decrement integers inside hashmaps?

I think the issue has to do something with the projectiles and explosions. I've tried adding the player into a hashmap but the same thing happens.

Hitting a mob and getting hit by a mob works but for some reason projectiles and explosions don't seem to work properly with the timer.
