Expose nullability requirements for PersistentProperty and PreferredConstructor arguments [DATACMNS-1513]

[spring-projects-issues]

Mark Paluch opened DATACMNS-1513 and commented

PersistentProperty and PreferredConstructor should indicate property/parameter nullability derived from JSR305 (@Nullable, @Nonnull) and Kotlin definitions.

We already provide NullableUtils to determine null/non-null defaults on type level. We should consider nullability indicators and type indicators (primitive types, Kotlin nullability) to express nullability or whether a constructor argument is required
