How to change language of the Save Parts dialog in eclipse e4 rcp?

Question

On closing a dirty part I get a Save Parts dialog. But there is appearently no way to change its header or the text "Select the parts to save:" message. My application is running with parameter -nl de so I expect this text to be in German, but this is not the case. Does anyone know how to localize this dialog?

For changing langage of default eclipse plugin, you need to install a plug-in like Babel (add your langage only: German) and add it to your product.

There is a German fragment for every Eclipse plug-in providing translation.
