When iterating over all nodes, you also pull the reference node (with id = 0), 
which probably doesn't have the requested property.
If you want to list all properties of a node, it's better to use a construct 
like:
for(String key: node.getPropertyKeys()){   
System.out.println(node.getProperty(key));}
