Annotation Interface WarnOnUnknownFields

@Retention(RUNTIME)
@Target(TYPE)
@Documented
public @interface WarnOnUnknownFields

Opts a type into a ConstructorCoercer check: a JSON property that does not correspond to any constructor parameter is logged as a warning instead of passing silently unnoticed. Unannotated types keep today's behavior — an unrecognized property is simply never looked at.
