Phillip Webb 55eba139ec Support binding of default properties when an empty property is defined Update the `Binder` so that empty properties are treated as an indicator that default value binding should be attempted. This update allow bound objects to differentiate between a completely missing property vs one that is present but doesn't have any values. For example, given the following value object: @ConfigurationProperties("my") public record My(Name name, int age) { public record Name(String first, String last) { } } The following binding scenarios are supported: 1) Full binding my.name.first=Spring my.name.last=Boot my.age=4 Binds to `new My(new Name("Spring", "Boot"), 4)` (works the same as Spring Boot 4.0) 2) Missing Properties my.age=4 Binds to `new My(null, 4)` (works the same as Spring Boot 4.0) 3) Default Properties my.name= my.age=4 Binds to `new My(new Name(null, null), 4)` (previously would throw a converter exception) Closes gh-48920		4 days ago
