This does partly. At least I was able to compile the whole borrowed Kaffe
classes tree (together with my trees). The problem is, Sun's tools still
remain proprietary and of big volume. The ideal case for me would be to find a
stupid (able to ignore absent classes and just forming constant pool entries),
small size Java compiler written in C (like guavac) with GPL or opensource
like license which just can be bundled with my distribution (this is a
question of distant future).

The JVM I've already partly written uses VERY late binding for java non-native
methods and classes (only when a constant pool entry needs to be resolved), so
such a stupidity of a Java compiler would be a plus for me (I just will get
runtime error on unimplemented methods / absent classes).
