ecj1 in cross-compile

Hello,

I've got my GCC 4.3 toolchain working ok now, but for some reason I
fail to get an ecj1 binary.

I'm cross-compiling for ARM and I've tried --with-ecj-jar=XXX (which
doesn't result in an ecj1) and also tried putting ecj.jar in my build
dir (which complains about a missing java compiler).
I must be doing something wrong, but I'm not sure what.

I expect an i686 ecj1 binary to be compiled from the ecj-latest.jar
that I download in my build. Preferably standalone, like the Ubuntu
one.
The build machine doesn't have an i686 GCJ or JAVAC installed, is that
a problem?

What am I missing?

Regards,

Matthijs
