Yeah, actually, you want to just run the provided /usr/bin/bootchart
script since that sets up the config properly:

[emparq at bart:~]$ bootchart
Parsing /var/log/bootchart.tgz
Wrote image: ./bootchart.png

...trying to launch it from just the .jar itself results in that error
you mentioned. I haven't explored any other way to generate my
bootchart, but running the script definitely works for me.
