I tried with the svn version of jclassinfo and with the version in Debian.

Debian versions of my files:
ii jclassinfo 0.19.1-4
extracts information from Java class files
ii openjdk-6-jre-headless 6b16-1.6.1-1
OpenJDK Java runtime, using Hotspot JIT (headless)

(I also reported the bug there:
http://sourceforge.net/tracker/?func=detail&aid=2865686&group_id=74004&atid=539646
some time ago without reaction yet).

Regards,
