RussianIt looks like it is a bug/limitation in version 4.3 of ProGuard. I have moved to version 4.4 and the problem is solved.
ProGuard fails with ArrayIndexOutOfBoundsException
Question
I'm using ProGuard during the build of a J2ME application. ProGruard fails during optimization with ArrayIndexOutOfBoundsException exception (see (1)).
The code that cause the failure is 'straintforward' : it is a method that copies 23 fields from one POJO to another (see (2)). In addition, when I comment some get/set statements, ProGruad doesn't fail (see (3)).
(1) ProGruard logs

(2) The method that fail
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;
}
(3) Commenting some lines of the method will make ProGruad not to fail
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;
}
