>          Issue Type: Improvement
>         Environment: ubuntu 8.0.4 java 1.6.0_11

> In case of a corrupt or faulty exif header, we should keep the well formed ones instead of propagating an IOException or an OutofMemory Error to the caller. Attached is a picture taken from an HTC handset, with a faulty exif thumbnail offset, causing an OutOfMemoryException. the patch in SANSELAN-17 turns it into an IOException and the good fields are still being lost.
> i.e we should have the following data instead of an exception
> Exif metadata:
> Root: 
>  Modify Date: '2010:10:05 22:51:03'

>  Unknown Tag (0x9208): 0
>  Unknown Tag (0x9004): '2010:10:05 22:51:03'
>  Unknown Tag (0x9207): 65535
>  Unknown Tag (0xa403): 65535
>  Image Height: 1552
>  Image Width: 2592
>  Make: 'HTC'
>  Exif Offset: 222
