JDK1.1.6L, AWT Core, Regression

Short description:
---------------------
When invoked from a Dialog, FileDialog does not return from show() until
focus changes, a key is pressed, or the mouse re-enters the calling
dialog.

This is a bad regression for JBuilder, as many of our PropertyEditors call
out to a FileDialog, and JBuilder appears as if it is locked-up until the user
clicks on a different application window.

Steps/Code:
---------------
Use the following code to show the bug (instructions embedded in the
code).

import java.awt.*;
import java.awt.event.*;
public class HangingFiler extends Dialog {
  public HangingFiler(Frame frame) {
    super(frame, "HangingFiler Dialog");
    setLayout(new BorderLayout());
    Button b = new Button();
    b.setLabel("click to invoke FileDialog");
    b.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        FileDialog fd = new FileDialog((Frame)getParent());
        System.out.println("- Showing FileDialog. Select any file and click
OK.");
        System.out.println(" - Show will not return until focus changes, a
key is typed,");
        System.out.println(" or the mouse enters the HangingFiler
dialog...");
        fd.show();
        System.out.println(" - Show returned. File=" + fd.getDirectory() +
fd.getFile());
      }
    });
    add(b, BorderLayout.CENTER);
  }
  public final static void main(String[] args) {
    HangingFiler hf = new HangingFiler(new Frame());
    hf.setBounds(400, 400, 300, 100);
    hf.show();
  }
}
