In this version we introduced the concept of property inheritance. It means that key-values pairs included in less specific files are inherited by those which are higher in the inheritance tree. For example: Let's assume you are using a en_US locale. if you have key-values in a generic
myResource.properties file, you can override them in a
myResource_en.properties and an even more specific
myResource_en_US.properties file. This opens up the possibility to define a generic language resource and define country specific translations in a more specific resource file.
