Hi Alex,
Could you clarify a little what you are trying to achieve functionally so we can provide guidance accordingly? The bootstrap approach is normally used with standalone UI5 applications and not really applicable to DS SDK components.
From the code snippet, it looks like you are trying to use the bootstrap approach to load the "sap.ui.commons" library. However, this is the exact purpose of using handler type "sapui5" when developing a UI5 based SDK component. The standard UI5 library is loaded for handler type "sapui5". Then if you need to access specific ui5 controls that are not automatically loaded you can use jQuery.sap.require.
Regards,
Mustafa.
