/usr/local/bin/jar?[arch alpha problems]

Hi,
Is there a 'jar' utility program in sablevm project? kaffe's jar utility 
throws on alpha:
# jar (/usr/bin/jar)
Internal error: caught an unexpected exception.
Please check your CLASSPATH and your installation.
java/lang/ArrayIndexOutOfBoundsException
Aborted
where , #cat  /usr/bin/jar
#! /bin/sh
prefix=/usr/lib/kaffe/pthreads
exec_prefix=${prefix}
exec ${exec_prefix}/bin/kaffe $JAVA_OPTS kaffe.tools.jar.Jar ${1+"$@"}
exit $?
fastjar works to unpack batik-1.5.1.zip per:
http://xml.apache.org/batik/install.html
but sablevm balks at using it to start the (batik)browser giving:
ref:(http://xml.apache.org/batik/svgviewer.html#browsing)
casey171:/home/mel/batik-1.5.1# java -fastjar batik-squiggle.jar
Warning: -fastjar option NOT RECOGNIZED by java-sablevm.
A not recognized option will be just passed to SableVM.
Note that we don't know if we should expect an argument after it.
It almost _surely_ will result in an errors when the param is followed
by an argument. Refer to 'man java-sablevm' and 'man sablevm'.
sablevm: "-fastjar" unknown option
Try "sablevm --help" for more information
-any help here appreciated-Mel
