Hi,

my recent change [1] triggered this problem with the runtime/valhalla/valuetypes/VboxUnbox.java test because if EnableMVT=true and EnableValhalla=false, TypeNarrowKlass::NULL_PTR is NULL although it's used by OptoRuntime::store_value_type_fields_Type() for multiple value return [2].

Best regards,
Tobias
