[kaffe] bugs in jar program

[Moses DeJong]

I compiled and installed kaffe from the CVS today. I also made a symlink
in my share/kaffe directory to the JDK's classes.zip file.


% setenv CLASSPATH /tmp/mo/install_kaffe/share/kaffe/Klasses.jar

% /tmp/mo/install_kaffe/bin/jar -cf0 Test.jar Test.class
security properties not found. using defaults.

#at this point an uncompressed jar has been created. I can read
#and extract its contents with the JDK's jar program correctly.
#but, when I run the kaffe version of the jar program it bombs!


% /tmp/mo/install_kaffe/bin/jar -xf Test.jar
java.lang.Error: unknown compression method

#jar will also bomb when creating a compressed archive
