JDK-8274735, JPEG compression in a TIFF container, openjdk/jdk/pull/7849

[Michal Karm]

Hello,

There used to be an Unsupported Image Type exception thrown
when one wanted to decode a TIFF container with JPEG compressed image.

That behavior has changed, there is no exception now, although the
resulting image is incorrect.

I outlined the details in this doc [1], including a small reproducer.

The test image is not anything from a fuzzer, it's just me
clicking Export As in GIMP.

Thanks for feedback

Cheers
Karm
