      public final class JMessage
      extends javax.swing.JDialog

  This component is similar to `javax.swing.JOptionPane` component. It can be used to display message and error dialogs. The main features of `JMessage` are:
  - Displays simple messages and the stacktrace of an exception
  - Supports html text for messages with build-in plain text conversion
  - The dialogs are modal. In addition they stay on top of other windows at all times
  - Supports for `JOptionPane` OK,CANCEL,YES,NO buttons
  - Selects a default button in the dialog
  - Supports all `JOptionPane` messageType(s) & optionType(s)
  - Uses UI default icons or user supplied icons
  - Uses localized dialog titles and button text, or user supplied text
  - Returns dialog status depending on which button was pressed
