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.

		List cpelements= fClassPathList.getElements();
		List libelements= new ArrayList(cpelements.size());
		
		int nElements= cpelements.size();
		for (int i= 0; i < nElements; i++) {
			CPListElement cpe= (CPListElement)cpelements.get(i);
			if (isEntryKind(cpe.getEntryKind())) {
				libelements.add(cpe);
			}
		}
		fLibrariesList.setElements(libelements);
