Here is my result using Kaffe 1.1.x-cvs:

/opt/bin/kaffe -cp . Test01 write  | /opt/bin/kaffe -cp . Test01 read
t1=Test01 at 81192f4 A B
t2=Test01 at 822fda4 A B

so, I decided to run prevayler's demo, and I got the following message:

$ /opt/bin/kaffe -cp ../prevayler2.01.000alpha.jar:.
org.prevayler.demos.demo1.Main
