Problem solved.
After another day of head scratching I tried, just for fun and giggles, to
change the default output from <bundlename>/target/classes to <bundlename>/bin,
and lo and behold, the Exception disappeared and the bundle starts again.
I have no idea what happened here, and I am not ready yet to try to figure that
out either...
Cheers,
Erwin
