      Description

        ADDITIONAL SYSTEM INFORMATION :
        Windows 10 with HiDPI display with everything scaled at 200%

        A DESCRIPTION OF THE PROBLEM :
        HTML tooltips aren't big enough to contain their contents on Windows HiDPI displays, so the final word on a line wraps to the next line. If it is a multi-line tooltip, then the final line is missing entirely.

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Run the attached program. Mouse over the button and wait for the tooltip to appear

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        The tooltip says "Some tooltip text"
        ACTUAL -
        The tooltip says "Some tooltip"

        ---------- BEGIN SOURCE ----------
        package com.company;

        import javax.swing.*;
        import java.awt.*;

        public class TruncatedTooltip {

            public static void main(String[] args) {
                // Demonstrate that the tooltip contents are truncated when the tooltip is lightweight (entirely within the window bounds) on Windows HiDPI displays
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                    JButton button = new JButton("toggle height");
                    button.setToolTipText("<html>Some tooltip text<html>");
                    JFrame frame = new JFrame();
                    frame.getContentPane().setLayout(new FlowLayout());
                    frame.getContentPane().add(button);
                    frame.setSize(400,200);
                    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
                    frame.setVisible(true);
                    button.addActionListener(e -> frame.setSize(300,frame.getHeight()<200?200:40));
                } catch (Exception e) {
                    throw new RuntimeException(e);
                }
            }
        }
        ---------- END SOURCE ----------

        CUSTOMER SUBMITTED WORKAROUND :
        Click the button which decreases the size of the window enough such that the tooltip needs to extend outside of the window bounds. It displays correctly as a heavy weight tooltip.

        This bug does not happen under Java 9.

        This bug does not happen if the Windows look and feel is not set.

        FREQUENCY : always
