Ошибка маскировки Proguard Maven с использованием выражений лямбда

Question

Я использовал Proguard с Maven для маскировки кода Java.

меняю все функции от анонимного заявления на Lambda expression0, но после компиляции и запуска я получаю ошибку

Интересный журнал ошибок:

Caused by: java.lang.invoke.LambdaConversionException: Type mismatch for lambda argument 1: class com.goodsoft.stockbox.commons.model.c is not convertible to int 

... так что, может быть, нет никаких проблем с Lambdas, но с маскированными объектами, использующими лямбда?

Метод ДО изменения лямбда выглядит (отлично работает):

bidAskDiffChangeObserver = new BidAskDiffChangeObserver(instrument, 
    new IDiffValueChangeDelegate() { 
     @Override 
     public void valueChanged(int newValue, ValueChangeType type) { 
      mainRangeAxis.updateSpread(newValue); 
     } 
    }); 

... и ПОСЛЕ изменения в лямбда-выражения (не работают):

bidAskDiffChangeObserver = new BidAskDiffChangeObserver(instrument, 
        (newValue, type) -> mainRangeAxis.updateSpread(newValue)); 

It вызывается:

int newValue = computeBidAskDifference(); 
ValueChangeType type = previousValue > newValue ? ValueChangeType.DROP : 
     previousValue < newValue ? ValueChangeType.GROWTH : ValueChangeType.EQUAL; 

if (delegate != null) 
    delegate.valueChanged(newValue, type); 

Какой вариант я должен использовать для добавления лямбда-состояния?

Без маскировки все работает нормально (с опцией -dontoptimize).

Мои варианты Proguard в pom.xml выглядеть следующим образом:

EDIT

Я попытался добавить Maven варианты, как -optimizations !method/removal/parameter и -optimizations !method/marking/static, но не помогают.

Answer 1

решаемые

Существует проблема с оптимизацией меняющегося перечислений в целое.

Просто отключите эту оптимизацию и отлично работайте.

<option>-optimizations !class/unboxing/enum</option>
