Storing default property values in a default.properties file sounds like 
a very good idea. Personally, I think the way properties are handled in 
the Derby code is developer-unfriendly with the mixture of hardcoded 
variables and Property objects. Every now and then, I have to 
text-search for a property name and see what the value of the 
alternative is. A properties file in derby.jar would make this much easier.

If possible, I think it would be good to use the same format for this 
file and derby.properties. Since the format of derby.properties has 
already been defined, I think it would be better to go with that than 
with xml. Just my $0.02.
