Thanks. We’re looking into it.
The BndProperties extension is getting decorated with the appropriate ExtraPropertiesExtension, but there have been some changes to how dynamic properties are looked-up (to make the look-up faster). What I’m seeing is that we’re checking BndProperties for dynamic properties (calling propertyMissing) before we check if ext is available from somewhere else. Since BndProperties#propertyMissing always returns something, bnd.ext is returning null instead of the ExtraPropertiesExtension instance.
