Opening a new bug, based on discussion with xianfa.deng@Eng. This bug
may be similar to Bug # 4124096 .

Also note, there is an escalation to get fix/patch for this problem,
Esc # 516395.

For more detail, pl refer to Comments section:

Here is some code that fails under native and runs under green threads,
i.e. modal dialogs do not work, under JDK 1.1.6, no Swing used.
I adapted it from the bug report 4124096.
Also included is the run script I used.


/*
 * ModalDialogTest.java
 * Dialog created with modality parameter set to true is not modal on
 * Solaris
 *
 */

import java.awt.*;
import java.awt.event.*;

public class ModalDialogTest extends Panel implements ActionListener {
    Dialog dialog = new Dialog(new Frame(), "Modal Dialog", true);

    public static void main( String[] argv ) {
        new ModalDialogTest();
    }

    public ModalDialogTest() {
    Frame frame = new Frame("Modal Dialog Test");
    Panel controlPanel = new Panel();
    Panel infoPanel = new Panel();
    Button showButton = new Button("Show Modal Dialog");
    Button testButton = new Button("Test");

    frame.setLayout(new BorderLayout());
    infoPanel.setLayout(new GridLayout(0,1));
// showButton.setOpaque(true);
    showButton.setBackground(Color.yellow);
// testButton.setOpaque(true);
    testButton.setBackground(Color.pink);
    controlPanel.add(showButton);
    controlPanel.add(testButton);
    infoPanel.add(new Label("Click the \"Show Modal Dialog\" button to display
a modal Dialog."));
    infoPanel.add(new Label("Click the \"Test\" button to verify dialog
modality."));
    frame.add(BorderLayout.NORTH, controlPanel);
    frame.add(BorderLayout.SOUTH, infoPanel);
    dialog.setSize(200,200);

    showButton.addActionListener(this);
    testButton.addActionListener(this);

    frame.addWindowListener(new WindowAdapter() {
    public void windowClosing(WindowEvent e) {System.exit(0);}
    public void windowClosed(WindowEvent e) {System.exit(0);}
    });

    frame.pack();
    frame.setSize(450, 120);
    frame.setVisible(true);
                      }

    public void actionPerformed(ActionEvent evt) {
        String command = evt.getActionCommand();

        if (command == "Show Modal Dialog") {
             System.out.println("*** Invoking JDialog.show() ***");
             dialog.setLocation(200,200);
             dialog.show();
        }
        else if (command == "Test") {
             System.out.println("*** Test ***");
        }
    }
}



run script:


#!/bin/ksh


unset CLASSPATH
unset LD_LIBRARY_PATH
unset JAVA_HOME

export THREADS_TYPE=${THREADS_FLAG:-native}_threads

#PROG=$(basename $0)
ARCH=$(uname -p)

case $1 in
-native)
    THREADS_TYPE=native_threads
    shift
    ;;
-green)
    THREADS_TYPE=green_threads
    shift
    ;;
esac

if [ -z "$JAVA_HOME" ]
then
    export JAVA_HOME=$M1HOME/vod/jre
fi

if [ -z "$CLASSPATH" ]
then
    if [[ $THREADS_TYPE = "native_threads" ]]
    then
        export CLASSPATH=$JAVA_HOME/lib/rt.jar:$JAVA_HOME/lib/i18n.jar:.
        CLASSPATH=$JAVA_HOME/lib/classes.zip:$CLASSPATH
        echo "Native threads"
    else
        export CLASSPATH=$JAVA_HOME/lib/rt.jar:$JAVA_HOME/lib/i18n.jar:.
        echo "Green threads"
    fi
fi

export LD_LIBRARY_PATH=$JAVA_HOME/lib/$ARCH/$THREADS_TYPE

# java interpreter options:
# -ms16m set heap starting size to 16 Mbytes

exec $JAVA_HOME/bin/$ARCH/$THREADS_TYPE/jre -ms16m ModalDialogTest



You will have to change JAVA_HOME to run the script.
