Hi! I simply use this code for it: public static void contributeApplicationDefaults(
MappedConfiguration<String, String> configuration) { ResourceBundle bundle = ResourceBundle.getBundle("Cpu"); Enumeration<String> e = bundle.getKeys(); while (e.hasMoreElements()) { String key = e.nextElement(); configuration.add(key, bundle.getString(key)); } } ApplicationDefaults override FactoryDefaults values, and it's not possibly breakdown library's logic, when we change SymbolSource service directly Mihail.
