JavaDoc comments for method MetalRootPaneUI.installUI state:
"Invokes supers implementation of installUI to install the necessary state
onto the passed in JRootPane to render the metal look and feel implementation
of RootPaneUI. This will also install a new LayoutManager on the JRootPane.
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If the windowDecorationStyle property of the JRootPane is other than
JRootPane.NONE, this will add a custom Component to render the widgets to
JRootPane, as well as installing a custom Border on the JRootPane."

Actually installUI method does not install LayoutManager.

Example below demonstrates this problem:
------------------example--------------------
import javax.swing.JRootPane;
import javax.swing.plaf.metal.MetalRootPaneUI;

public class test {
    public static void main(String[] args) {
        JRootPane pane = new JRootPane();
        pane.getUI().uninstallUI(pane);
        pane.setLayout(null);
        MetalRootPaneUI ui = new MetalRootPaneUI();
        ui.installUI(pane);
        if (pane.getLayout() == null) {
            System.out.println("LayoutManager: " + pane.getLayout());
            System.out.println("Test failed");
        } else {
            System.out.println("Test passed");
        }
    }
}
------------------output---------------------
LayoutManager: null
Test failed
---------------------------------------------
