I could not reproduce this on RC2, here is what I did: - dl eclipse modeling RC2 - install Papyrus - start eclipse and exit Can you give details so that I can reproduce and fix this ?
You probably need to open a Sample Ecore Editor and perhaps an Xtext editor to have some action bars to observe.
Fixed in r4828: Several handlers did not test (PlatformUI.getWorkbench().getActiveWorkbenchWindow() == null) which occurs during exit.
Fixed in r4828
I think this is somewhat related to bug #356469.
