solaris: default FileDialog title is not empty

The FileDialog spec says the following about the FileDialog(Frame)
constructor:

  public FileDialog(Frame parent)
     Creates a file dialog for loading a file. The title of the file dialog
     is initially empty.
      Parameters:
         parent - the owner of the dialog


However, a FileDialog created by using this constructor does *not* have
an empty title.
On Solaris, a FileDialog created by using this constructor has a title of '_popup', and on winNT, it has a title of 'Open'.

The spec and the implementation are not in agreement.

The attached application (FileDialogTest.java) demonstrates this.
To recreate, press the 'Test FileDialog(p)' button.
