Description

Currently when the image size cannot retrieved from metadata we issue:

LOG.warn("No image metadata, will decode image and use raster size"); 

and

LOG.warn("Error reading image metadata, will decode image and use raster size", ex);

both at the warn level, but since these are recoverable errors (by using the raster size, as the messages indicate), I think their log priority should be reduced to info or debug. This is particularly important in the second message since it actually prints the full stack trace, which heavily pollutes log files.

I use JPEGFactory inside a server side application without control from which files the user uploads, and these stack traces are useless and distracting.
Thank you.
