Unusual "Resource not found" on some files

[Abdeali Kothari]

I seem to be getting an error which says "java.io.IOException: Resource not found: <file_url>" even when the file definitely exists. I'm also sure that the file url is correct.

I was using it to bulk test some JPG files on wikimedia to test for corner cases - You can find the travis log at https://travis-ci.org/AbdealiJK/file-metadata/jobs/136607124

It happens for:
- https://commons.wikimedia.org/wiki/File:Tour_revolver.jpg
- https://commons.wikimedia.org/wiki/File:Plateau_universel.jpg

I am using the javase version. My command is:

java -cp /home/ajk/.local/share/file-metadata/zxing/core-3.2.1.jar:/home/ajk/.local/share/file-metadata/zxing/javase-3.2.1.jar:/home/ajk/.local/share/file-metadata/zxing/jcommander-1.48.jar com.google.zxing.client.j2se.CommandLineRunner --multi file:///home/ajk/Downloads/Tour_revolver.jpg

The whole error message is:

That was really dumb of me. I didn't read the "Numbers of source Raster bands and source color space components do not match" in the 6th line of the error for some reason. Never mind ...
