I tried to extend the test (with this PR changes included) for all installed
L&Fs and then create the menu for each L&F.
UIManager.LookAndFeelInfo[] lafs = UIManager.getInstalledLookAndFeels();
for (final UIManager.LookAndFeelInfo lafInfo : lafs) {
System.out.println("installed laf className : " +
lafInfo.getClassName());
System.out.println("installed laf Name : " + lafInfo.getName());
menuBar.add(createMenu(lafInfo.getClassName(), lafInfo.getName()));
}
Then the test failed with this exception
java.lang.NullPointerException: Cannot invoke
"java.awt.Font.hashCode()" because "font" is null
at
java.desktop/sun.font.FontDesignMetrics$MetricsKey.init(FontDesignMetrics.java:213)

java.desktop/sun.font.FontDesignMetrics.getMetrics(FontDesignMetrics.java:282)

java.desktop/sun.swing.SwingUtilities2.getFontMetrics(SwingUtilities2.java:1235)
Otherwise the RBMI and CBMI does contain the icon after the fix.
