Using RubyMine to run a test suite, and althogh the test will run, the test runner will not show any progress, and the left-hand pane will not show any test nodes and what their status is. It just reports that "Test framework quit unexpectally". Attached is a screen shot.
Also, below is the full output, in case that helps as well. I am also using Rails 4 on JRuby 1.7.9 in 2.0 mode.
