title: Groovy is not displaying output on command line
body: <p>I unsuccessfully attempted to install Groovy 1.8.6 (zip distribution) on a Win XP (sp3) machine yesterday and today (the error messages stated it was unable to find the groovyStarter then I received a lengthy stack trace...). Needless to say, it was a frustrating experience. So, I decided to use the Windows installer for version 1.8.5. Groovysh functions as it should but if I write a small Groovy script and place it in a file:</p>
  
  <p><code>
      println "Hello Groovy Programmer!"
  </code></p>
  
  <p>...no output is displayed. Using groovy -e "println 'Hello!'" has the exact same behavior.</p>
  
  <p>Any ideas of what might cause this?</p>
  
  <p>Thanks.</p>
