[bormoshka]

Lombok version: 1.16.20 / 1.18.4
jdk: 1.8.181
code example: https://github.com/bormoshka/lombokTest/blob/master/lombok_1.16.20/src/main/java/ru/ulmc/lombok/fails/ValTypeFail.java

public class ValTypeFail {

    public void config() {
        val columnBool = createColumn(entity -> entity.getABoolean()); // this is working!
        val column = createColumn(Entity::getValue); // and here an error occurs
    }

    private <V> Column<Entity, V> createColumn(Function<Entity, V> func) {
        return new Column<>(func);
    }

    private static class Column<T, V> {
        public Column(Function<T, V> vp) {}
    }

    public static class Entity {
        @Delegate
        private MyDelegate innerDelegate;
    }

    @Getter
    @Setter
    public static class MyDelegate {
        private String value;
        private Boolean aBoolean;
    }
}

error: ValTypeFail.java:14: error: Cannot use 'val' here because initializer expression does not have a representable type: Type cannot be resolved
val column = createColumn(Entity::getValue); // and here an error occurs

UPD: IntelliJ idea lombok plugin see no error here:
