[Bug AWT/19861] New: Swing JOptionPane without parent frame

[hendrich at informatik dot uni-hamburg dot de]

The following testcase shows a (subtle) problem in the Swing rendering strategy.
A JOptionPane dialog without any parent works fine, but a JOptionPane
attached to a non-showing parent (e.g. JFrame) fails with an 
IllegalComponentStateException. Because the Exception blocks the Swing
redraw thread, there is no way to recover from the illegal state.

(both dialog windows work fine under JDK 1.4.2, not tested with other versions).


/* NoParentJOptionPane.java
 *
 * demonstrates GCJ doesn't like dialogs without visible parents...
 *
 * (C) 2005 FNH
 */

import java.awt.*;
import javax.swing.*;

public class NoParentJOptionPane {

  public static void main( String args[] ) {
    String s = "Testing JOptionPane w/o parent...";

    System.out.println( "The first call works: null parent:" );
    JOptionPane.showMessageDialog( null, s );

    // JDK1.4+ runs this, gcj complains about:
    // java.awt.IllegalComponentStateException: component not showing
    // at java.awt.Component.getLocationOnScreen() 
    // at javax.swing.SwingUtilities.convertPointToScreen(java.awt.Point,
java.awt.Component) 
    // at javax.swing.SwingUtilities.convertPoint(java.awt.Component, int, int,
java.awt.Component) (/usr/lib/lib-javax-swing.so.0.0.0)
    // ...
    JFrame frame = new JFrame( "just a hidden frame" );

    System.out.println( "The second call is broken: frame parent" );
    JOptionPane.showMessageDialog( frame, s );

    System.exit( 0 );
  }

}

I have checked in a fix for that some days ago in GNU Classpath.
