Re: compiling ant to a native binary

This is interesting. I worked on a large J2EE project (thousands of classes, hundreds of thousands of lines of code) for two years until Feb. 2002, using jikes to compile and Jikes never hit any "bad" byte code.

Fwiw, I've read on several occasions that the byte code generated by
jikes isn't always reliable. I don't know why or under what
circumstances it produces "bad" code, but for that reason alone, I
won't use jikes and would caution others to be careful.

I'll throw in a "me too", although it's been at least a year since I
last tried jikes.

There are certainly things that Jikes will not compile that Javac will. Largely odd corner cases involving protected methods.
Jikes also uses a different way of compiling constructors, which trips up some tools.
Further Jikes does not use the same patterns when compiling inner classes, so often if you mix jikes compiled classes with javac compiled classes you'll get NoSuchMethodErrors or even VerifierErrors when you try to run. Obviously, if you stick to one compiler, your problems will be less!

I see this every day at work (~ 5000 classes in the project). Its been a couple of versions since Jikes could even compile our whole source tree without segfaulting.

All this aside the main problem with jikes is that it appears to have been abandoned. No one is paid to maintain it anymore, and the volunteers are not making much headway that I can see. All of the energy now seem to be directed at the compiler sub project within Eclipse (not my opinion, actually that of someone on the jikes development mailing list).
