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/PropertyAndPreferencePage.java
return fProject;

	final void doLinkActivated(Link link) {
		if (isProjectPreferencePage()) {
			openWorkspacePreferences(NO_LINK_DATA);
		} else {
			HashSet projectsWithSpecifics= new HashSet();
			try {
				IJavaProject[] projects= JavaCore.create(ResourcesPlugin.getWorkspace().getRoot()).getJavaProjects();
				for (int i= 0; i < projects.length; i++) {
					IJavaProject curr= projects[i];
					if (hasProjectSpecificOptions(curr.getProject())) {
						projectsWithSpecifics.add(curr);
					}
				}
			} catch (JavaModelException e) {
				
			}
			ProjectSelectionDialog dialog= new ProjectSelectionDialog(getShell(), projectsWithSpecifics);
			if (dialog.open() == Window.OK) {
				IJavaProject res= (IJavaProject) dialog.getFirstResult();
				openProjectProperties(res.getProject(), NO_LINK_DATA);
			}
		}

		PreferencesUtil.createPreferenceDialogOn(getShell(), id, new String[] { id }, data).open();
