How can we change the default icons used for the application built-in actions?
If you look inside the main JAR library [OXYGEN_DIR]\lib\oxygen.jar or [OXYGEN_DIR]\lib\author.jar it contains an images folder in which all the images which we use for our buttons, menus, and toolbars exist.
You can use this mechanism to overwrite any kind of resource located in the main oXygen JAR library. The folder structure in the endorsed directory and in the main oXygen JAR must be identical.
