Hmm. 

Just to make sure, I just changed JOptionPane to use FlowLayout instead 
of BoxLayout, and while the resulting dialog (from PR24080) is not pretty, 
at least it shows something... see attached screenshot.

I still haven't a clue why BoxLayout is broken (in this one case) for me,
but not for everybody else.


javax/swing/JOptionPane.java


  public JOptionPane(Object message, int messageType, int optionType,
                     Icon icon, Object[] options, Object initialValue)
  {
    this.message = message;
    if (! validMessageType(messageType))
      throw new IllegalArgumentException("Message Type not legal value.");
    this.messageType = messageType;
    if (! validOptionType(optionType))
      throw new IllegalArgumentException("Option Type not legal value.");
    this.optionType = optionType;
    this.icon = icon;
    this.options = options;
    this.initialValue = initialValue;

-   setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
+   setLayout( new FlowLayout( FlowLayout.LEFT ));
