It is possible to stop the start of the application by returning false in @PostContextCreate. It is also possible to use the key e4.osgi.exit.code in the application context to set a return value if the application gets shut down normaly.

Combining these features, you would expect the following to restart the application.

@PostContextCreate
Boolean postContextCreate(IEclipseContext context) {
	context.set(Constants.EXIT_CODE, IApplication.EXIT_RESTART);
	return false;
}

To solve the issue I would like to:
- change E4Application so the return value is also calculated after @PostContextCreate retuns false
- make the constant EXIT_CODE public API

In addition to this, I would also like to make the RestartPreferenceUtil public, so that it is possible to use it like this:

@PostContextCreate
Boolean postContextCreate(IEclipseContext context, RestartPreferenceUtil restartPref) {
	restartPref.setClearPersistedStateOnRestart(true);
	context.set(Constants.EXIT_CODE, IApplication.EXIT_RESTART);
	return false;
}

This is similar to Bug 421153, as it adresses the same need, but has a different approach to the solution.
