Be careful of licensing issues here -- did you get the javac compiler
source from Sun? The source license is pretty restrictive. AFAIK,
there are no docs on it.


Also -- you may be better off writing a pre-processor to do assertion
processing. (Stick in method calls for assertion constructs).


Pre-processors are used quite a bit for this sort of thing -- also,
saying that you're modifying the compiler to support a superset of
Java can leave a very bad taste in many people's mouths -- this is
more like changing the Java language, which is a big no-no. A
pre-processor makes it clear that the feature isn't part of the real
language, just an add on.


BTW: There's a java 1.1 grammar (with a few minor bugs) for ANTLR 2.x at
http:www.antlr.org which might provide a decent starting point...)
