Java NIO Problem

Hello all.

My problem seemingly is that the Set<SelectionKey>'s iterator is not
removing the key when done. This *appears* to be what is wrong. Here is
some code:

    public void run()
    {
        //SelectionKey key=null;
        //Set<SelectionKey> selectedKeys=null;
        //Iterator it=null;

        while(true)
        {
            try
            {
                if(selector.select(500)==0)continue;

                Set<SelectionKey> selectedKeys=selector.selectedKeys();
                Iterator it=selectedKeys.iterator();

                while(it.hasNext())
                {
                    SelectionKey key=(SelectionKey)it.next();

                    if(key.isValid())
                    {
                        if(key.isReadable())
                        {
                            readFromSocketChannel(key);
                        }
                    }

                    it.remove();
                }
            }
            catch(IOException ioe)
            {
                ioe.printStackTrace();
            }
            catch(Exception e)
            {
                System.out.println(e);
            }
            finally
            {
                //it.remove();
                //key.cancel();
            }

What ends up happening is the readFromSocketChannel(key) just keeps
getting called with an empty buffer after the first actual read.

Help appreciated! :-)
