org.apache.tika.exception.TikaException while trying to get images' metadata ...

 After reading this post:

~
 getting metadata from files using tika seemed easy. Right now what I
am most interested in is images but all tika gives me is:
~
org.apache.tika.exception.TikaException: Can't read JPEG metadata
 at org.apache.tika.parser.image.ImageMetadataExtractor.parseJpeg(ImageMetadataExtractor.java:92)
 at org.apache.tika.parser.jpeg.JpegParser.parse(JpegParser.java:66)
~
org.apache.tika.exception.TikaException: image/png parse error

~
org.apache.tika.exception.TikaException: image/gif parse error
 at org.apache.tika.parser.image.ImageParser.parse(ImageParser.java:91)

 I am using tika-app-0.9

 How could you read metadata from files? Do you have any true code examples?

 Hmm! But, why do I have then so many corrupted files?

 Some of these files I had even grabbed from the Internet for my tests

This sort of thing is normally caused by corrupt images. Are you able to 
share any of your problematic files?
