A DESCRIPTION OF THE PROBLEM :
Nested JOptionPane.showInternalXxx return default value immediately.

While another modal internal frame exists, JOptionPane.showInternalXxx does NOT wait the selected value.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
parent confirm start
child confirm start
----- Expected is waiting until user input
child confirm end
parent confirm end

ACTUAL -
parent confirm start
child confirm start
child confirm end -1
---- child confirm does not wait and return -1 immediately
parent confirm end

REPRODUCIBILITY :
This bug can be reproduced always.

public class Test {
public static void main(String[] args) {
final JDesktopPane desktop = new JDesktopPane();
JButton button = new JButton(
new AbstractAction("do parent confirm") {
public void actionPerformed(ActionEvent e) {

System.out.println("child confirm end " + childRC);
}
}
)
}
);
System.out.println("parent confirm end " + parentRC);
}
}
);
button.setBounds(10, 10, 200, 20);
desktop.add(button);
desktop.setSize(400, 300);
desktop.setPreferredSize(desktop.getSize());
final JFrame frame = new JFrame("test frame");
frame.setContentPane(desktop);
frame.pack();
frame.setDefaultCloseOperation(JInternalFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
do not return when (nativeContainer.modalComp != null) at Container#startLWModal
or
make sure to wait the value after startLWModal call backed at JOptionPane#showInternalInputDialog
