It's not clear to me why you'd get a NullPointerException wrapping the IndexOutOfBoundsException, but this is the problem: for (int i = 1; i < messwerte.size(); i ++ ) { g.setColor(Color.MAGENTA); ... more 2/19/2015 7:07:42 PM

This is what's killing you: task.Wait(); That's blocking the UI thread until the task has completed - but the task is an async method which is going to try to get back to the UI thread after it "pauses" and awaits an async result. It... more 2/19/2015 8:36:44 AM

It's not just MSDN that uses the term "default constructor" specifically for a constructor which is supplied either "if you don't specify anything else" or "always, for a struct (pre C# 6)" or "always, for a struct, unless you specify your... more 2/19/2015 7:15:04 AM
