BTW the test can be simplified to something like this UIManager.setLookAndFeel(new MetalLookAndFeel()); JToolTip tp = new JToolTip(); tp.setTipText("<html><h1>Hello world</h1></html>"); tp.setMinimumSize(new Dimension(1, 1)); tp.setMaximumSize(new Dimension(1, 1)); tp.setPreferredSize(new Dimension(1, 1)); tp.setBounds(100, 100, 1, 1); BufferedImage img = new BufferedImage(100, 100, TYPE_INT_ARGB); Graphics2D g2d = img.createGraphics(); tp.paint(g2d); g2d.dispose(); ------------- PR: https://git.openjdk.java.net/jdk/pull/2761
