okay, how about:
class Boolean {
Class TYPE = VMLoader.BooleanTYPE;
}
with VMLoader on gcj being something like:
class VMLoader {
Class BooleanTYPE = boolean.class;
}
and VMLoader on sane VMs being:
class VMLoader {
Class BooleanTYPE = VMLoader.loadPrimitiveClass("boolean");
}
This has a total time over head of *nine loads*, executed *once* at the
beginning of the program. Total space overhead is *nine words* (eleven,
if you need a header for VMLoader). I think even your 28K system can get
by with this.
I don't see why portability is so difficult.
