A DESCRIPTION OF THE PROBLEM :
Swing dialogs are displayed in English instead of the system language. In Java 1.8 it worked as expected, with the same source code.
REGRESSION : Last worked in version 8u211
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Execute the source code below
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Buttons are labeled in system language (in German: "Ja" and "Nein"), like it does under Java 1.8
ACTUAL -
Buttons are labeled in English ("Yes" and "No")
---------- BEGIN SOURCE ----------
import javax.swing.JOptionPane;
public class SwingTest {
public static void main(String[] args) {
JOptionPane.showConfirmDialog(null, "Test", "Test", JOptionPane.YES_NO_OPTION);
}
}
---------- END SOURCE ----------
FREQUENCY : always
