Error when trying to view bpmn file in Eclipse with flowable plugin NoSuchMethodError: 'void org.eclipse.draw2d.FigureCanvas.setScrollbarsMode(int)'

Question

I have Eclipse 2024-12 4.30 for Enterprise Java and Web Developers. I have installed the flowable plugin using http://www.flowable.org/designer/update/

In my project that I started by importing a local git repository, I get this error when trying to view a bpmn file:

This has happened with multiple versions of Eclipse.
