BaseConfiguration.getProperty() returns reference to intenal store collection
object instead of a clone
-------------------------------------------------------------------------------------------------------
Key: CONFIGURATION-224
URL: http://issues.apache.org/jira/browse/CONFIGURATION-224
Project: Commons Configuration
Issue Type: Bug
Environment: 1.3RC2
Reporter: Gabriele Garuglieri
Priority: Minor
Attachments: list.patch
When the property object is a List or an Array, BaseConfiguration.getProperty()
returns a reference to the object contained in the store.
This means that changing that object, changes the content of the properties
store without an explicit setProperty() or addProperty().
Also any change to the object in the store will change the object that the code
has reference to, but the user is not aware that the property has changed
unless he has added a ConfigurationListener.
Attached a patch to make the object returned by BaseConfiguration.getProperty()
a clone of store content, to avoid side effects when changing Collection
properties.
