Thanks Marc. The additional changes look good but I found some more places that need adjustment. Search for `IsInit`, all occurrences need to be adjusted. I think they can simply be replaced by `null marker`.

src/hotspot/share/opto/inlinetypenode.hpp line 51:

Suggestion:

         NullMarker, // Needs to be checked before using the field values.
