GH-398 - Fix Association deserialization with implicit property-based creators

[ogawa-takeshi]

Summary

Fixes #398.

When Jackson 3 auto-detects a public parameterized constructor as an implicit property-based creator, it uses the constructor parameter types for deserialization. This causes failures when the constructor parameter type (e.g. an AggregateRoot) differs from the bean property type (Association).

This commonly occurs with jMolecules ByteBuddy plugin, which adds public no-arg constructors to entity classes for JPA. Jackson 3 then sees both the no-arg constructor and the original public parameterized constructor, selecting the latter as an implicit creator.

Changes

• SingleValueWrappingTypeDeserializerModifier: Added updateBuilder() override that detects when a property-based creator parameter type mismatches an Association-typed bean property, and:

  1. Disables the implicit property-based creator (wraps ValueInstantiator to return false for canCreateFromObjectWith())
  2. Replaces the wrongly-typed property in the builder with one derived from the setter or field (which has the correct Association type)

• JMoleculesModuleUnitTests: Added test reproducing the issue with a class that has a public constructor whose parameter name matches an Association-typed field.

Test plan

• New test deserializesAssociationWithImplicitCreator passes
• All existing tests pass (9 tests, 0 failures)
