YouTrack beta does not work for me

On OS X I start YouTrack from the command line with the following command:

java -Xmx256m -jar youtrack-1.0-beta.jar 8080

It seems to start ok and after a short while and lots of logging output it tries to open the following url in Safari:

http://localhost:8080/loginForm

That's when it starts to fail and a bunch of exceptions are printed on the console. Here is an example:

14:45:54,234 INFO  [ResourceBundle                ] [btpool0-1      ] Create new resource budle [text/css]

14:45:54,235 INFO  [Resource                      ] [btpool0-1      ] Create new resource [jetbrains/mps/webr/runtime/css/Default.css]

Did I do something wrong or should I file a bug?
