  *     Description:    Exception breakpoint
  *     Steps:          1.Set caught exception breakpoint on class
  *                       javax.sound.midi.MidiUnavailableException
  *                     2.Debug Main

  *
  * When the test is starting debugee, debugger creates <code>ExceptionRequest</code>.
