eclipse rcp - Exception while executing zest sample of gef5

Question

Version I use: jdk11 jfx11 eclipse202012R gef5.3.2

When I run any of the zest examples, I throw an exception when I drag and move the node.

Can anyone help me?

If anyone can give a MVC model or examples that can be applied, it will be the best. Here's the exception, when I run org.eclipse.gef.zest.examples.SimpleExample, Drag and node:
