Eclipse 4 rcp load layout not works with binding context - eclipse

Question

I have an application, in which I can save the load perspective layout.
Everything works until I add Binding Context to any Part. If I set Binding Context to part, then save layout, then close application and try to load layout in opened application again I get exception:
!ENTRY org.eclipse.e4.ui.workbench.swt 4 2 2016-10-16 20:54:37.922

here is my steps:
test handler class:
public class Test {
#Execute
public void execute(EPartService partService) {
System.out.println("Test handler");
}
}
Create handler:
Then create Binding Contect, Binding table with KeyBinding
finally add BindingContext to part:
Loading and saving layout code is same as in this tutorial Model persistence article 3
Maybe someone knows what problem can be and is there are any solution?
