I have tried closing a session using a CloseUISessionCommand but this doesn't reliably close the session. The only thing that seems to work is calling a close directly on the session (e.g. session->close), but this always generates the following IllegalStateException:
05:04:43:134 EDT at 31-Aug-2017 WARNING bundle:org.eclipse.sirius Thr:1 Error while unloading an unaccessible resource:

It would be a great help if someone can explain the best practice as I haven't seen any standard documentation on this.

Hello
Which version of Sirius do you use? I bet that will not reproduce with sirius5 because we don't unload the resource any more at close.
You said Quote:using a CloseUISessionCommand ... doesn't reliably close the session .
What do you mean? Could you detail what's wrong? This command will save the session if needed and close the opened editor and then close the session.
Nevertheless, this command is internal. Session.close() is the recommended way to close a session.
Do you have a reproducible scenario?
Regards
