Think those existed for some older java version not sure. But I still look
forward to a patch.

That's a stripped binary? If I make a redhat 9 rpm I hope it can use the
redhat installed gcj.so, probably it's also possible to compile it
staticaly (or only do gcj.so statically). And what's 2.6 Mb nowadays ;)
Advantage of using gcj is that it comes default nowadays with most linux
distributions, this unlike java for which you have to dig around first.
Also no classpath trouble. No trouble in figuring out you'd have to run
antlr.Tool etc. It would also open the opportunity for distributions to
ship antlr with/in place of pccts.

Cheers,

Ric
