以下のコードは、以前のバージョンでは問題なく動作しますが、Java 7 にアップグレードした後は動作しませんでした。

誰でも助けることができますか？

コード:

if (imageFile.exists())

System.out.println(imageFile.getPath()+" :"+ imageFile.getName());
      // prepare to read the input

final FileInputStream fis = new FileInputStream (imageFile);  

ImageInputStreamiis=null;
iis = ImageIO.createImageInputStream(fis);          
final Iterator<ImageReader> imageReaders = ImageIO.getImageReaders(iis);
ImageReader reader = imageReaders.next();
reader.setInput(iis, true, false);

ここで基本的に同じ問題である質問に答えました: Java 7 に切り替えた後、 ImageIO メソッドが機能しません。

唯一の違いは、この例外がImageInputStreamSpiとして登録されようとしているために発生することImageReaderSpiです。
