GenJar 1.0.1, had an annoying regression where the exception message did not contain the name of the class that couldn't be resolved.
GenJar 1.0.1 was release.
1.0.1 fixes several important bugs.
See http://genjar.sourceforge.net for more information.
GenJar finally hits 1.0.
GenJar has been stable for some time, and with the recent addition of a full testing infrastructure, GenJar is more solid than ever.
