Oh, the syntax highlighting, yes, welder (arc editor that comes with rainbow) can htmlify arc code so that it's easy to paste into a blog or other web page; then it's just a matter of a little CSS to decide what colour you want for different kinds of tokens.
You can just comment out the (run-all-tests) line in rainbow-libs.arc, but you're right, it should be optional somehow.
Let me know how you get on with accessing java libs, I've tried to make it as simple and concise as possible, so that your code still looks like arc code and not some outrageous contaminated half-blood hybrid monstrosity ...
