Java Virtual Machine crashes

Im using SCO OpenServer 5.0.7 operating system. My JVM is version 1.4 and also I have 1.5

When I'm trying to input a character in range 0x80 - 0x9f in GUI Text field, my JVM loads the CPU up to 100%, and the only way to stop It is to kill the jvm process.

When I input character in same range in java console application, It is all fine.

I'm guessing there is a diffrence how jvm interpetating console stdin and GUI key events.

Does anybody have an idea, how can I fix this problem?

I dont beleave, It is a program flow. Here is a standart example which crashes:

// TextForm.java

import javax.swing.JPanel;
import javax.swing.JLabel;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JTextField;

import java.awt.Insets;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.BorderLayout;
import java.awt.Container;

import java.awt.event.*;

public class TextForm extends JPanel {

   private final JTextField[] tf;

   // Create a form with the given labels, tooltips, and sizes
   public TextForm (String[] labels, String[] tips, int[] widths) {
      tf = new JTextField[labels.length];

      setLayout (new GridBagLayout());
      final GridBagConstraints gbc = new GridBagConstraints();
      gbc.anchor = GridBagConstraints.WEST;
      gbc.insets = new Insets (3,3,3,3);

      // Add labels and fields as specified
      for (int i=0; i<labels.length; i++) {
         final JLabel l = new JLabel (labels[i]);

         // Create an accessibility-friendly field
         tf[i] = new JTextField (widths[i]);
         tf[i].setToolTipText (tips[i]); // sets accessible desc too!
         l.setLabelFor (tf[i]);          // sets accessibleName for tf[i]!

         // lay out label & field
         gbc.gridy = i;
         gbc.gridx = 0;
         add(l, gbc);
         gbc.gridx = 1;
         add(tf[i], gbc);
    }
  }

   // Get the contents of one of the TFs.
   public String 开发者_如何学PythongetEnteredText(int index) {
      return tf[index].getText();
   }

   // A simple example program
   public static void main(String[] args) {
      final String[] labels = { "First Name", "Middle Initial", "Last Name", "Age" };
      final String[] descs = { "First Name","Middle Initial", "Last Name", "Age" };

      final int[] widths = { 15, 1, 15, 3 };

      final TextForm form = new TextForm(labels, descs, widths);

      // A button that dumps the field contents
      final JButton dump = new JButton("Dump");
      class DumpListener implements ActionListener {
         public void actionPerformed(ActionEvent ev) {
            System.out.println(form.getEnteredText(0));
            System.out.println(form.getEnteredText(1));
            System.out.println(form.getEnteredText(2));
            System.out.println(form.getEnteredText(3));
         }
      }
      dump.addActionListener (new DumpListener());

      final JFrame f = new JFrame("Text Form");
   //   frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); // Requires Java 1.3
      final Container c = f.getContentPane();
      c.setLayout (new BorderLayout());
      c.add(form, BorderLayout.CENTER);
      c.add(dump, BorderLayout.SOUTH);
      f.pack();
      f.setVisible(true);
  }
}

The problem is that, jvm crashes at the moment the key event is made, so I cannot debugg it from within my program.

There might be a disparity between the two environments with regard to the default Charset. I've noticed that NetBeans, Eclipse and many consoles can be set to something other than the platform default. It couldn't hurt to check:

System.out.println(System.getProperty("file.encoding"));
System.out.println(Charset.defaultCharset().name());
