You can have 2 NPEs with this code, because :

- "knows" try to be feed with activeChar's knownlist, even if activeChar isn't ingame.

- "knows" try to search for an object, but imagine you try to enchant in a place where there is no one around ?

 

Correct way is to initialize Collection after the null check, just before the "for". And to include a null check in if (wh instanceof L2WarehouseInstance)

 

So we got (I didn't verify where you putted your "for" loop, let's say it was good) :

 

final Collection<L2Character> knowns  = activeChar.getKnownList().getKnownCharactersInRadius(400);
for (L2Object wh : knowns)
{
    if (wh != null && wh instanceof L2WarehouseInstance)
    {
        activeChar.sendMessage("You cannot enchant near warehouse.");
        return;
    }
}
