ClassCastException with ImageNodeStyleDescription

Try to reproduce this bug after the next update of Sirius-Web in Papyrus-Web

You need to be on the commit 0e80e9ee on Papyrus-Web:

• Create a Papyrus-Studio Project
• Go into the Component Diagram
• Create a Sub-Node in the SHARED_DESCRIPTIONS folder
• Go into this new subNode (don't edit it)
  • Delete the created RectangularNodeStyleDescription
  • Create a new ImageStyle (ImageNodeStyleDescription) instead (don't define the associate Shape)
• Reference the SubNode as a new Compartment of Interface (rootNode and SubNode)
• Create a new UML Model
  • Create a Component Diagram
  • Create Interface
    • all works fine, but the interface only have 3 Compartments and not yet 4
• Return into the Studio, and edit the SubNode like this:
  • domainType : uml::Element
  • semanticCandidateExpression: aql:self
• Now return in your model
  • If I remember well, the existing diagram with Interfaces will be broken with an exception
  • Create a new Component Diagram and create an Interface inside it:

    • The interface will be semantically created, but won't appear in the diagram

    • You terminal will display an exception like this:
