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.

			fDisabledProjectSettings= new IdentityHashMap();
			for (int i= 0; i < allKeys.length; i++) {
				Key curr= allKeys[i];
				fDisabledProjectSettings.put(curr, curr.getStoredValue(fLookupOrder, false, fManager));
			}
