I compared the dgminfo files from groovy-all.jar in stable and unstable, in unstable the 0x0D bytes have been replaced by 0x0A. It looks like the file was erroneously processed as a text file and the line terminators were transformed.
I fail to see what change in jarjar 1.4 caused this though. Emmanuel Bourg __ This is the maintainer address of Debian's Java team <http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-java-maintainers>. Please use debian-j...@lists.debian.org for discussions and questions.
