just posted a fix for a NPE in case a empty RobotRuleSet is used.
The patch only contains a two lines fix, since I learned that this
best way to get things committed sooner. :)
However I really don't like the RobotRuleSet implementation since
entries are copied between a arraylist and a array for just no
reasons. from my point of view.
I would love to change that to just use the arraylist.
Can I have a vote from one committer that would commit that to the
source in case I do this change? :-)
