LinkedBlockingQueue czyli jak napisać pulę JDBC

protected LinkedBlockingQueue<Connection> pool = new LinkedBlockingQueue<Connection>();

public Connection getConnection() throws SQLException {
  long timeToGo = connAcquireTimeout;
  long start = System.currentTimeMillis();
  Connection conn = null;
  int size = poolSize.get();
  workerThread.orderConnections(size < poolMinSize ?
   poolMinSize - size : 1);
  // wkladamy do kolejki roboczej watku
  // ilosc polaczen do zrobienia;
  // watek w metodzie run wyjmuje Integer-a n,
  // robi n polaczen i wklada je do pool-a
  
  while (true) {
  try {
    conn = pool.poll(timeToGo, TimeUnit.MILLISECONDS);
    break;
  }
  catch (InterruptedException ie) {
    if (conn==null) {
      long runTime = System.currentTimeMillis()-start;
      if (runTime < timeToGo)
        timeToGo -= runTime;
    }
  }}
  return conn;   
}
