Hello! I am working on getting the Discourse app to run in JRuby, and need to replace its dependency on rinku.

There are two ways we typically do this:

• Port the extension. This shouldn't be difficult, but it seems like you may have already done this work?
• Wrap a JVM library.

The latter would be preferable, since all we'd need to write is a bit of Ruby to wrap your library.

However there's a few things that would make this integrate better with JRuby:

• CharSequence is great, but the API produces String eventually. This means JRuby's byte[]-based Ruby strings need an extra conversion step, which will obviously slow down the rendering of a large document.
• Compatibility with rinku. I'm not sure how to map the features of rinku to autolink-java and will need some tips here.

Here's a quick and dirty rinku-like wrapper based on your example code from README. It can serve as a place to start discussing: https://github.com/headius/jruby-autolink
