it seems everything is in there...

$ ls /usr/lib/sablevm/sablevm-classpath

So it must be the debian developer of sablevm that is sucking! ;-)

Guys, here is a test case. Attached is a simple build.xml you can run
with ant.

1=B0 run by kaffe:

$ JAVACMD=3D/usr/bin/kaffe ant

Unable to locate tools.jar. Expected to find it in /usr/lib/kaffe/lib/tools=
.jar
Buildfile: build.xml

init:
     [echo] What time is it? 20040409 - 2253

BUILD SUCCESSFUL
Total time: 1 second

(the first line is because of ant 1.6, I don't know why?! but everything
runs fine)

2=B0 The same with java-sablevm

$ JAVACMD=3D/usr/bin/java-sablevm ant

Warning: -Xmx512M option not implemented in java-sablevm wrapper.
Unable to locate tools.jar. Expected to find it in ?/lib/tools.jar
Buildfile: build.xml
