Description

Copying an XMLConfiguration using the ConfigurationUtils.copy() method does
not work if there are repeated keys. The end result is an XMLConfiguration
with a majority of its properties missing because only the first property
value for a repeated key is copied to the configuration.

This can be repeated by taking the example database tables XML file on the
Jakarta Commons Configuration webpage, loading the configuration into an XML
configuration, creating a new XMLConfiguration using the empty constructor,
copying the first to the second using the ConfigurationUtils.copy() method,
and then perform the property queries as described on the webpage. For
example, calling getProperty() for 'tables.table(2).name' will fail on the new
configuration after the original configuration is copied.

This copying is the basis of my entire implementation because I want to be
able to copy an XMLConfiguration without having to go to the operating system
and reload a copy from disc.
