java.lang.StringIndexOutOfBoundsException: String index out of range: 4544

`public String getPurchaseOrderForVendor(String contractAddress,String accountAddress, String 
vendorName)
{

    TransactionManager tx = getTransactionManager(accountAddress);
    Tuple3<List<BigInteger>, List<BigInteger>, List<byte[]>> result;
    try
    {

        InvoiceSettlement_sol_InvoiceSettlement dm = InvoiceSettlement_sol_InvoiceSettlement.load(contractAddress, quorum, tx, GAS_PRICE, GAS_LIMIT);
        result = dm.getPurchaseOrderForVendor("name").send();

    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return "somereturnvalue";
}`

web3j v 3.3.1 , solidity 0.4.21.

The error java.lang.StringIndexOutOfBoundsException: String index out of range: 4544 occurs when i am returning a byte[] from a function in solidity. i am using ganache-cli and tested the same code with quorum also.

I have a similar problem, I don't know if it's the same problem or not. I wrote a post also in the Ethereum StackExchange (https://ethereum.stackexchange.com/questions/42927/string-returned-from-mapping-of-struct-array) but with no success, my code should work fine... For every transaction, I store some information in this struct:

struct MoneyTransfer{
    address sender;
    string comment;
    uint creationTime;
    uint quantity;
}
struct Transfers {
        MoneyTransfer[] structArray;
      }
mapping(address => Transfers) private moneyTransferMap;

For each address, the first "comment" string returned by the Java wrapper is this one:

"\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000�\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0004"

Another strange thing: after putting another object in the same array, if the first "comment" string was a long one (80 chars), when I try to get the data with the Java wrapper, I get this error:
