## [Java] Class LegacyHashMapPropertyHandler

- groovy.transform.options.LegacyHashMapPropertyHandler

-     public class LegacyHashMapPropertyHandler
      extends ImmutablePropertyHandler

  The `@Immutable` transformation in earlier versions of Groovy tried to be smart in the case of an immutable class with a single HashMap property, the supplied Map constructor tried to be compatible with both expected tuple behavior and expected named-argument behavior by peeking into the supplied map and guessing as to which approach might be applicable. Recent versions of Groovy now allow both `@TupleConstructor` and `@MapConstructor` annotations to co-exist which provide's a more flexible solution to this problem. While more flexible, the new approach isn't fully compatible with the previous approach. If for some reason you need the old behavior, you can try this property handler. Some features of the new approach won't be available to you.

  Since:
    2.5.0
