code: protected final void fireVetoableChange(String propertyName,
              long oldValue,
              long newValue)

docs: Support for reporting changes for constrained integer properties. This method can be called
  before a constrained property will be changed and it will send the appropriate
  PropertyChangeEvent to any registered VetoableChangeListeners.
  
  @param propertyName the property whose value has changed
  @param oldValue the property's previous value
  @param newValue the property's new value
  @throws PropertyVetoException if a constrained property change is rejected
