It is under your own control to break the recursion: Your component will only have to call Configuration Admin configuration if such configuration is not provided through the activate or modify method, i.e. only if such update is induced externally. BTW: for your sample use case of UI location you might want to look into the OSGi Preferences Service specification which sounds more appropriate for such configuration (which generally is different per user).
