Description Steve Monnier CLA 2018-02-28 08:13:22 EST 
It is possible to customize the tabbar of diagram using the org.eclipse.sirius.diagram.ui.tabbarContributor. The contributor associated can extend AbstractTabbarContributor to select which default tabbar action will be available. Adding createSelectMenuManager() to the Diagram Contribution causes an NPE when a diagram element is selected and Eclipse is restarted.

Step to reproduce:
- Import the project in attachment
- Launch a runtime
- Open a diagram and select a diagram element
- Restart Eclipse (Set breakpoint on NPE)
-> It should not cause an NPE in SelectionService

I said that the issue happens when Eclipse is restarted, but it also happen when Eclipse is closed of course.
