Redcar redcar

== Problem: Starting from a clean installation of Redcar (meaning gem install redcar and redcar install), redcar will not start up properly. From the console, I get a Java exception and Ruby stack trace immediately after the redcar splash/loading screen. Following the error message, the splash screen disappears automatically but no additional window is displayed.

== Supporting details: The complete console output is as follows:

After killing the process with C-c, I am returned to my shell prompt without issue (no need to kill the process externally).

== Expected behavior Not knowing enough about the internals of Redcar, I am unable to say whether the exception and the failure of any subsequent windows to appear are related. However, one would expect Redcar to start without error and to display a window so that further interaction with Redcar can take place.

== Notes It would be my pleasure to provide any additional information to help the developer team resolve this issue.
