John,

      In answer to your question, it would be very nice for you to make the
jazzlib .jar file you suggested, and, yes, it should include the
java.util.jar.* classes.  We have dropped our own (very partial) zip
implementation, and now use jazzlib by default.

 The error message when using `-cp .' seems to be a bug, and most likely
one I introduced.  I shall investigate.

I'm trying to build JRVM from CVS and I got the following error:

I then made up a jazzlib .jar file and added this line i686-pc-linux-gnu:

export JAZZLIBJAR=/mnt/dev/jikesground/jazzlib/jazzlib.jar

Then I got this error:

I rebuilt the jazzlib jar file to include the GNU Classpath java/util/jar
classes.
Then the image built successfully

However running rvm resulted in some kind of recursion and failure, the
errors seemed to appear when reading the Manifest of the jar file.

I rebuilt the jar file using the IBM dk's jar command (previously I used
fastjar) and this time I could run rvm (but I had to set the directory with
pwd):

bapli% rvm -cp $(pwd) trivial

bapli% rvm -cp . trivial

Cannot find repository for /mnt/dev/jikesground/build1/trivial.class
java.lang.ClassNotFoundException: trivial

What I want to know is:

Would it be useful if I created a .jar file as part of the jazzlib release
files (so that the version used by JRVM is the same as the one on the
jazzlib page)? Should I include the java.util.jar classes in such a .jar
file?

Thanks
