that's good to hear.

looks like we need to fix FAQ.embedded ;)
export JAVAC="/usr/java/jdk1.3.1_08/bin/javac"
is the one you need, flags are set separately.

And then ./configure --with-jikes=$JAVAC

make JAVAC_FLAGS="-g:none -bootclasspath lib/ "
results in a nice 300k smaller rt.jar for me, with javac from 1.3.1

the errors come from javac trying to load core system classes from its 
bootclasspath, i.e. Sun's implementation and the internals of the 
implementation are different (no surprise here, kaffe is a clean-room 
effort). In order to fix it, you need to supply it with a bootclasspath 
that points to the classes being compiled. Just take a look at the
