A DESCRIPTION OF THE PROBLEM :
Using a Synth Look and Feel, JCheckBoxMenuItem cannot resize after setHorizontalTextPosition. This occurs only with jdk 1.8.0_152 or higher. With JDK 1.5.0_151 or older the problem doesn't occur.

REGRESSION : Last worked in version 8u172


---------- BEGIN SOURCE ----------
// Set synth look an feel

                JFrame frame = new JFrame();
frame.setTitle("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JMenuBar menuBar = new JMenuBar();
JMenu menu = new JMenu("Options");
                JCheckBoxMenuItem colorKeyCheckBox = new JCheckBoxMenuItem();
colorKeyCheckBox.setSelected(false);
colorKeyCheckBox.setMnemonic(KeyEvent.VK_K);
colorKeyCheckBox.setText("Show Color Key");
colorKeyCheckBox.setHorizontalTextPosition(JCheckBoxMenuItem.LEADING);
colorKeyCheckBox.setVerticalTextPosition(JCheckBoxMenuItem.CENTER);

                menu.add(colorKeyCheckBox);

                menuBar.add(menu);

frame.setJMenuBar(menuBar);
frame.setPreferredSize(new Dimension(500, 500));
frame.pack();
frame.setVisible(true);
