Ошибка ProGuard с ArrayIndexOutOfBoundsException

Question

Я использую ProGuard во время сборки приложения J2ME. ProGruard не работает во время оптимизации с исключением ArrayIndexOutOfBoundsException (см. (1)).

Код, вызывающий отказ, является «принудительным»: это метод, который копирует 23 поля из одного POJO в другой (см. (2)). Кроме того, когда я комментирую некоторые инструкции get/set, ProGruad не терпит неудачу (см. (3)).

(2) Способ, который потерпеть неудачу

public static TransactionEntityShadow convertFromLegacy(TransactionEntity legacy) { 
     TransactionEntityShadow result = new TransactionEntityShadow(legacy.getService(), legacy.getAliasCode()); 

     result.setAliasCode     (legacy.getAliasCode()); 
     result.setAmount     (legacy.getAmount()); 
     result.setBeneficiaryAccountNumber (legacy.getBeneficiaryAccountNumber()); 
     result.setBeneficiaryId    (legacy.getBeneficiaryId()); 
     result.setBeneficiaryIdTypeId  (legacy.getBeneficiaryIdTypeId()); 
     result.setBeneficiaryMSISDN   (legacy.getBeneficiaryMSISDN()); 
     result.setBeneficiaryName   (legacy.getBeneficiaryName()); 
     result.setBeta      (legacy.getBeta());

     result.setSessionKey    (legacy.getSessionKey()); 
     result.setTransactionDate   (legacy.getTransactionDate()); 

     return result; 
    } 

(3) Комментируя несколько строк метода сделает ProGruad не потерпеть неудачу

public static TransactionEntityShadow convertFromLegacy(TransactionEntity legacy) { 
     TransactionEntityShadow result = new TransactionEntityShadow(legacy.getService(), legacy.getAliasCode()); 

     result.setAliasCode     (legacy.getAliasCode()); 
     result.setAmount     (legacy.getAmount()); 
     result.setBeneficiaryAccountNumber (legacy.getBeneficiaryAccountNumber()); 
     result.setBeneficiaryId    (legacy.getBeneficiaryId()); 
     result.setBeneficiaryIdTypeId  (legacy.getBeneficiaryIdTypeId()); 
     result.setBeneficiaryMSISDN   (legacy.getBeneficiaryMSISDN()); 
//  result.setBeneficiaryName   (legacy.getBeneficiaryName()); 
//  result.setBeta      (legacy.getBeta()); 
//  result.setBillContractNumber  (legacy.getBillContractNumber()); 
//  result.setBillNumber    (legacy.getBillNumber()); 
//  result.setBillSecretCode   (legacy.getBillSecretCode()); 
//  result.setContractBeta    (legacy.getContractBeta()); 
     result.setCustomerKey    (legacy.getCustomerKey()); 
     result.setFeesAmount    (legacy.getFeesAmount()); 
     result.setFreeByte1     (legacy.getFreeByte1()); 
     result.setFreeByte2     (legacy.getFreeByte2()); 
     result.setLanguageIndex    (legacy.getLanguageIndex()); 
     result.setMerchantCode    (legacy.getMerchantCode()); 
     result.setMerchantServiceCode  (legacy.getMerchantServiceCode()); 
     result.setPinDigest     (legacy.getPinDigest()); 
     result.setService     (legacy.getService()); 
     result.setSessionKey    (legacy.getSessionKey()); 
     result.setTransactionDate   (legacy.getTransactionDate()); 

     return result; 
    } 

Answer 1

Похоже, что это ошибка/ограничение в версии 4.3 ProGuard. Я перешел к версии 4.4, и проблема решена.

Answer 2

Использование -dontoptimize в вашем ProGuard
