first, congrats on becoming a TLP!
through my usage of buildr on different platforms, i discovered that rjb is a very tricky solution. it relies on loading java through jni, a mechanism that is not very often used and so is not available on some platforms (most painful and not yet working is hpux) and requires hacking on others. jruby is not a very good alternative because it slows down the build considerably.
maybe there can be another alternative: by running the jvm normally and using nailgun to communicate with it, passing object to/from similarly to what rjb does. what do you think?
