Hi
First--if necessary, am glad to file a bug for this, but wanted to
check and see if there was something I'm missing.
In trying to render a table of characters using their Unicode
identifiers, I found that the character \u0DDD crashes my JVM as soon
as it is rendered to a Swing component. I'm not particularly
interested in that character--I am just trying to print out different
characters in different fonts to easily track which glyphs are
available per font. I found this by accident. I'm writing to this list
as I suspect (but don't know) that it may be an issue with the font
system.
java -version
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) Client VM (build 11.0-b15, mixed mode, sharing)
Ubuntu 8.10
uname -r
2.6.27-7-generic
Small app that shows the problem:
import javax.swing.*;
import javax.swing.border.LineBorder;
import java.awt.*;
import java.awt.event.ActionEvent;
public class TestChar {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new TestChar().run();
}
});
}
private void run() {
JFrame frame = new JFrame("Test Character");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
final JLabel label = new JLabel("(empty)");
label.setSize(400, 100);
label.setBorder(new LineBorder(Color.black));
JButton button = new JButton("Set Char x0DDD");
button.addActionListener(new AbstractAction() {
public void actionPerformed(ActionEvent actionEvent) {
label.setText(Character.toString('\u0DDD'));
}
});
panel.add(button);
panel.add(label);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
}
}
Run this, then click the button. On my Ubuntu system, clicking the
button causes an immediate crash of the VM. Have also tested on OS X
java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06-153)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_07-b06-57, mixed mode)
and the VM _did not crash_.
Output in the Ubuntu console following the crash is attached.
If I should just file a bug for this, please let me know.
Thanks!
Patrick
