我在构建J2ME应用程序时使用ProGuard。 ProGruard在使用ArrayIndexOutOfBoundsException异常进行优化期间失败（参见（1））。
导致失败的代码是＆＃39; straintforward＆＃39; ：这是一个将23个字段从一个POJO复制到另一个POJO的方法（参见（2））。另外，当我评论一些get / set语句时，ProGruad不会失败（参见（3））。

（2）失败的方法
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());

}
（3）评论该方法的某些行将使ProGruad不会失败
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;
}

看起来它是ProGuard 4.3版中的错误/限制。我已经转到4.4版本，问题就解决了。

在你的proguard中使用-dontoptimize
