I have no idea. This is strange. But I assume it has something to do
with me releasing 1.12.4, or the preparation for automatic snapshot
realeases. I just don't know what I did to cause it. I have looked
through the releases, and it seems only 1.11.6 is broken.
I have uploaded new files with checksums in sync to resolve this.
Hopefully they should appear in Maven soon. It is less than ideal that
those files won't match the original ones, but it's the best I can do.
Thanks for spotting this!
