JPCAP：EXCEPTION_ACCESS_VIOLATION

Question

我正在使用JPCAP代码在pcap文件中写入数据包（我使用的是JDK 1.7）。这是代码

      JpcapCaptor captor=JpcapCaptor.openDevice(device[index], 65535, false, 20);
       //open a file to save captured packets
            JpcapWriter writer=JpcapWriter.openDumpFile(captor,"yourfilename");

                for(int i=0;i<10;i++){
         //capture a single packet
         Packet packet=captor.getPacket();
        //save it into the opened file
              writer.writePacket(packet);
         }

而不是在pcap文件中保存数据包。它给我以下错误
