Crashing after running the specs on JRuby 1.7.3

[batasrki]

The environment is JRuby 1.7.3 on Mac OS X 10.8.4, with rbenv 0.4.0. I've included the stack trace, the Gemfile and the Guardfile.

The gist of it (no pun intended) that the specs run, but the process crashes complaining of not having rb-fsevent. Including or not including the gem in the Gemfile seems to make no difference. I believe that the dependency comes from the listen gem that the guard-jruby-rspec gem depends on.

Any help would be appreciated.
