Bug 82231 [build path] Hard to find type restriction compiler problem preferences
I20050104-1600 There compiler preference page contains a Warning/Error node with many sub-entries . I tried to find where I could change the 'warning' for the access of internal types to 'error'. No luck until I realized that the Build node also contains Warning/Error settings.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/OptionsConfigurationBlock.java
private Key fKey;
		private String[] fValues;
		
		public ControlData(Key key, String[] values) {
			fKey= key;
			fValues= values;
		}
		
		public Key getKey() {
			return fKey;
		}
