How restart RCP application with -clearPersistedState. [message #1385493]

I'm working on e4 (kepler) RCP application based on compatibility layer.

I want to restart my RCP application with -clearPersistedState option programmatically.

But by default

PlatformUI.getWorkbench().restart()

doesn't have any option to restart with clearPersistedState.

Is there is any other way to do this, even any workaround will also be helpful.

Thanks.

our workaround for this (not using the compatibility layer though) is:

wrap the E4Application in your own implementation of IApplication (E4Application is internal API, so you will have to ignore the "discouraged access")
before calling IWorkbench.restart() -> save a flag as a preference
on starting the application: check if your flag is set. If so, set the system property E4Workbench.CLEAR_PERSISTED_STATE to true and clean your preference flag.

System.setProperty(E4Workbench.CLEAR_PERSISTED_STATE, "true"); //$NON-NLS-1$

Hope this helps!
