Hello Dennis,

Are you sure you're using the new code, as this is exactly the same line that I fixed?

Stepping though the code is a matter of launching the JVM with remote debugging parameters
and then connecting to it from Eclipse. Should be pretty straightforward.

Greetings, Marcel

I did not have time myself to look into it yet, but that should be in ace-obr-metadata. I'll
try to look into it when I have time, but feel free to supply a patch if you've figured it
out before me!
