Hi Olivier,

Sirius has not yet been adapted to E4. For my information, where do you
see that PlatformUI.getWorkbench() singleton pattern is incompatible
with E4? If you can provide a reproduction scenario with a test data,
you can raise a bugzilla about your issue with all these informations to
allow us to analyze it.

Best Regards.
