(with no warning)

Yes, I do think they are loading the right classes. With -verbose, I see:
Loading java/net/SocketImpl.class(/tmp/kaffe-with-kjc/jre/lib/rt.jar) 
[compressed]
or
Loading 
java/net/SocketImpl.class(/tmp/kaffe-with-tamed-jikes/jre/lib/rt.jar) 
[compressed]

And the rt.jar files do differ:

$ ls -l /tmp/kaffe-with-tamed-jikes/jre/lib/rt.jar
-rw-r--r--    1 daniel   daniel    2401618 Apr 16 20:41 
/tmp/kaffe-with-tamed-jikes/jre/lib/rt.jar
$ ls -l /tmp/kaffe-with-kjc//jre/lib/rt.jar
-rw-r--r--    1 daniel   daniel    2504817 Apr 16 21:00 
/tmp/kaffe-with-kjc//jre/lib/rt.jar

BTW, I had to give --without-jikes to configure to get kaffe use kjc. It 
seems the default is jikes.
I put /tmp/kaffe-with-tamed-jikes/bin before building kaffe-with-kjc.
