Firstly, `cancelCellEditing()` is dependant on CellEditor being non-null since everywhere it is called via `getCellEditor().cancelCellEditing()` and `cellEditor` is transient which does not participate in serialization

and 
secondly, `editorRemover` is  PropertyChangeListener object and in other places in jdk like
https://github.com/openjdk/jdk/blob/5f083abafc7abfaa46ddd053668cdfbfd2ad8a87/src/java.desktop/share/classes/java/beans/beancontext/BeanContextSupport.java#L1436
https://github.com/openjdk/jdk/blob/5f083abafc7abfaa46ddd053668cdfbfd2ad8a87/src/java.desktop/share/classes/javax/swing/JFileChooser.java#L281
it also doesn't participate in serialization so have done the same
