    Description

      In current ConnectionPool.getConnection(), it will return the first active connection:

      for (int i=0; i<size; i++) {
        int index = (threadIndex + i) % size;
        conn = tmpConnections.get(index);
        if (conn != null && !conn.isUsable()) {
          return conn;
        }
      }
      

      Here "!conn.isUsable()" should be "conn.isUsable()".
