Incompatibility between 3.x and 4.x in InternalPlatform [message #1723413]

I am getting the following exception on platform shutdown in 4.x.
It seems the relevant change (from 3.x to 4.x) is in

org.eclipse.core.runtime.Plugin.savePluginPreferences()

In 4.x, org.eclipse.core.internal.runtime.InternalPlatform.getInstanceLocation() is called which checks if the platform is initialized. In 3.x there is no call to InternalPlatform.getInstanceLocation() within Plugin.savePluginPreferences()

It seems that whenever the Platform is shutdown before any other UI plugin (AbstractUIPlugin), the exception below will be thrown.

Question: does the RCP product have to make sure that all UI plugins are shutdown before InternalPlatform.stop() is called or is this a bug in 4.x as it does not handle InternalPlatform.initialized properly?
