Why do I get an ArrayIndexOutOfBoundsException? (Solved)

I've got the code from: https://launchpad.net/gpxrenderer

Tried to run it with my own .gpx and then I get:

ArrayIndexOutOfBoundsException: 0 >= 0

Invalid input: `?' (0xfeff), SystemID='file:.', Line=1

I've did read the topics about this problem, but i'm too noob to know how to solve it.

Maybe my .gpx file has to many tracks for the array?

Love to get some input from someone to whom it does make sense.

Here is the code:
