out.scriptPubKey().addresses() is null

[jayjacklin]

List txList = block.tx();
if(!CollectionUtils.isEmpty(txList)){
for(String tx:txList){
BitcoindRpcClient.RawTransaction transaction= client.getRawTransaction(tx);

                List<BitcoindRpcClient.RawTransaction.Out> outList= transaction.vOut();
                for(BitcoindRpcClient.RawTransaction.Out out:outList){
                    List<String> addresses=out.scriptPubKey().addresses();
                    System.out.println(addresses);
                }
            }
        }

addresses is null ，There is an address parameter in scriptPubKey
