> Make it possible to run multiple instances of Derby within the same VM, each with its
own derby.system.home, separate configuration parameters, and even different versions of Derby
jar files. I haven't looked at this carefully, but at first glance I think this would require
(a) refactoring Derby code to get all configuration from a configuration API rather than directly
from system properties (b) write a configuration API/class that supports a properties file
as well as system properties (in the future this class could also work with JMX) (c) the ability
to specify the derby.system.home and a classpath as a DataSource property (d) a Derby classloader
that loads Derby jar files from the classpath specified on the DataSource
