I think the usability value in getting back what you put it is greater 
than having the keys rearranged on you (given the order of the keys is 
not significant to the implementation).

Why do you think rearranging them is more usable?

The restrictions on characters in ObjectName and the subsequent quoting 
mechanism are a consequence of the overloading between values and 
patterns. If we simplify the API and get rid of the latter then we no 
longer need any additional restrictions inside Geronimo.

There is a clear conversion between a GBeanName and an ObjectName: any 
keys or values that contain characters that are illegal in JMX can be 
quoted and escaped /in JMX/; GBeanNames that are legal ObjectNames can 
be used as-is.

Of course, we would recommend that users stick to simple names that are 
compatible with both but there is no need to enforce JMX restrictions on 
a non-JMX implementation.
