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.

fLibrariesList.setButtonsMinWidth(buttonBarWidth);
		
		fLibrariesList.getTreeViewer().setSorter(new CPListElementSorter());
		
		fSWTControl= composite;
				
		return composite;

	private Shell getShell() {
		if (fSWTControl != null) {
			return fSWTControl.getShell();
		}
		return JavaPlugin.getActiveWorkbenchShell();
	}
