javax.imageio.IIOException: Bogus marker length

读取图片时抛异常，解决方法：删掉本地图片，重新跑测试，正常；
 

异常信息：

javax.imageio.IIOException: Bogus marker length

伪代码：

//文件名后缀长度
int typeLen = imagePath.substring(imagePath.indexOf(".") + 1).length();
//文件类型
String type = imagePath.substring(imagePath.length() - typeLen);
BufferedImage bm = ImageIO.read(
                    new BufferedInputStream(
                        new FileInputStream(
                            new File(imagePath))));
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ImageIO.write(bm, type, bos);
