Marcel,

I see that you fixed this error, however I am getting another one now that is similar (see
below).

Additionally, I would like to be able to step through the code in Eclipse. Maybe I missed
the documentation for that somewhere?

Error in C:\path\Apache-Ace\ace-devserver\store : Low Range is higher than High Range: 4.1.3-4.1.3
java.lang.IllegalArgumentException: Low Range is higher than High Range: 4.1.3-4.1.3

is "org.apache.ace.discovery.property" and the single key you need to supply is "serverURL".

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!
