17:14:01 [INFO] This error is logged only once: it could have occurred multiple times by now.

and here is the rollback function and some other stuff:

Code:

@Override
    public void run() {
        try {
        rollback(); // line 70
        } catch(Exception e) {
           
        }
    }
   
    public void rollback()    {
        while(count < allLines.size()) {
            for(String line : allLines) {
                rollback(line); // line 79
                count++;
            }
        }
    }

If you need more, i'll update my github repository so you can look at the whole file.
thanks in advance,

Try:

Code:

public synchronized void rollback()    {
        while(count < allLines.size()) {
            for(String line : allLines) {
                rollback(line); // line 79
                count++;
            }
        }

 

Hmm, that didn't work

 

do bukit methodes on the main thread, instead on your own thread ( dont whine about the lagg, the problemsn that can exist now are mutch worse, )

 

i don't whine about the lag but it worked before... but i think since the changes in bukkit R1.4 with the synchronous and asynchronous events that might cause it, i don't know much about that part of java so i don't know for sure.

you used your own thread for it, the chance dont affec tit
The stack trace whould be diferend if that was the cause

 

ok, than i think i will have to live with the lag, i fixed it already so....Thanks

now the permissions.....:/
