Kaffe is a GPL Java Development Kit similar to Suns JDK. I don't think
it works as well, and it obviously causes some problems. You can either
rename the /usr/bin/jar to jar.old or something or do an rpm -e kaffe to
get rid of the entire development kit. Since you have this problem make
sure that you are actually using the JDK you thought you were by doing a
java -version. If it says Blackdown something or 1.1.7, etc then you're
using a Blackdown/Sun Port, otherwise if it says Kaffe... you're still
using Kaffe.
