That probably means the class has ben compiled for Java 5 (although
build.properties says 1.4?). What version of Maven are you using? Right
now the project has been ported to M2. I havent removed the old POM
(project.xml) yet, but the maven 1 build should be broken.

Have you tried the ready-to use jar from the SF project page? Try that
one; in the meantime i'll finish up with the maven 2 port and you'll be
able to build on java 1.4.

hth,
