IllegalArgumentException under Java 1.8

[jgaskins]

Using a fresh RVM-installed JRuby on a fresh JDK 1.8 installation on OS X Mavericks, I received this error:

➜  Code  mirah fib.mirah
java/lang/reflect/Constructor.java:408:in `newInstance': java.lang.IllegalArgumentException
    from /Users/jamie/.rvm/gems/jruby-1.7.13/gems/bitescript-0.1.4/lib/bitescript/mirror.rb:208:in `load'

Full backtrace here. I'm posting it here rather than on the Mirah project because the exception happened from within a bitescript file; I hope that's okay.

The contents of fib.mirah don't matter — it gave the same exception regardless of what it had in it. It didn't even work with -e.

Relevant versions:

It's fine to post it here. The next release of Mirah won't be using bitescript anymore as it'll be completely self hosted.

I'm guessing it's fairly straightforward, but I don't have much time to look at it right now.
