Bundle is not recognized in NetBeans 8.2

Hi,

Moving my module to NetBeans 8.2 from NetBeans 8.0.2 and Bundle is not recognized:

public TestClassesTopComponent() {
        initComponents();
        setName(Bundle.CTL_TestClassesTopComponent());
        setToolTipText(Bundle.HINT_TestClassesTopComponent());
        OpenProjects.getDefault().addPropertyChangeListener(this);
        tree.setModel(createTreeModel(false));
    }

What should I do?

Thanks a lot.
