I found that after creating a new partition I cannot save the server.xml. I get an odd error which looks like a URL resolution problem with the XML dumper. Perhaps some API call has a malformed URL or something in dom4j. Here's the error message:
An error occurred when writing the file to disk.
can't resolve URL: null
I can give more feedback after seeing the XML it generates from the GUI elements.
P.S. I will keep evaluation with new versions to give feedback - just keep emailing me.
