REPRODUCIBILITY :
This bug can be reproduced always.

PUBLIC COMMENTS I used the following test to reproduce the bug: ------------ package crs.cr6945177; import javax.swing.*; public class Text6945177 { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { public void run() { try { UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); } catch (Exception ex) { ex.printStackTrace(); } JTextField textField1 = new JTextField(30); JTextField textField2 = new JTextField(30); JPanel content = new JPanel(); content.add(textField1); content.add(textField2); JFrame frame = new JFrame(); frame.setContentPane(content); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.pack(); frame.setVisible(true); } }); } } ------------ Unfortunately I can't reproduce the bug. I analized the stacktrace from the bug and found out that code in the Utilities.getTabbedTextOffset method was fixed in CR 6857057. Try a new jdk build and observe that the error disappeared.
