Java中使用JPBC库进行ABE的EOFException

Question

我正在尝试使用eclipse：JPBC ABE中使用的JPBC库运行基于属性的加密示例。当我运行代码时，我得到以下错误

      @RequestMapping(value = "menu9data", method = RequestMethod.POST)
                public JSONObject view(@RequestPart(name = "file", required = false) MultipartFile image,@Valid MenuData model, BindingResult results)  {
        String name1;
          FFmpegFrameGrabber g = new FFmpegFrameGrabber("/home/anupam/Downloads/"+name1);  //Error
                                    g.setFormat("mp4");
                                    try {
                                        System.out.println("enterss");
                                        g.start();
                                    } catch (Exception e) {
                                        // TODO Auto-generated catch block
                                        e.printStackTrace();
                                    }
                                    for (int i = 0 ; i < 1 ; i++) {
                                      /*  try {
                                        //  ImageIO.write(((Object) g.grab()).getBufferedImage(), "png", new File("/home/anupam/Downloads/"+name1+"snap"));
                                        } catch (IOException e) {
                                            // TODO Auto-generated catch block
                                            e.printStackTrace();
                                        } catch (Exception e) {
                                            // TODO Auto-generated catch block
                                            e.printStackTrace();
                                        }*/
                                    }
                                     try {
                                        g.stop();
                                    } catch (Exception e) {
                                        // TODO Auto-generated catch block
                                        e.printStackTrace();
                                    }
        }
}

我已经包含了所有必要的库。我该怎么办呢？
