Comment 2 Martin Janicek 2012-10-10 10:05:48 UTC 
I've fixed the NPE in web-main: #56e224e4eed5

..but there is still a problem with type interference (println is a static method used from another class which is imported by default - because of that our current support is not able to find the correct type where the method belongs to).. I'll create another issue to track this as it's different problem than this one

I've created issue 219817 to track the type interference problem
