I like the test, you have almost hand rolled your own specializer :-) A minor point. Since you have created a ClassWriter with "ClassWriter.COMPUTEMAXS | ClassWriter.COMPUTEFRAMES" can you remove the "mv.visitMax(0, 0)" calls? no, you can't. even if you ask ASM to compute the maxs, you still need to call visitMaxs() or kitten will die.

Ah, i see now, it's the arguments to visitMax that are ignored and not the call itself.

Thanks, Paul. -------------- next part -------------- A non-text attachment was scrubbed...
