web3j Tutorial – Solve Unmatched Arguments Error While Generating Java Wrapper Class in web3j

That opcode is a recent addition to geth in the Constantinople release. You need to add the following to your genesis to enable Constantinople:

     "constantinopleBlock":0,

Take a look at the code generated by the wrappers

Function name() for a ERC20

    public RemoteCall<String> name() {
        final Function function = new Function(FUNC_NAME, 
                Arrays.<Type>asList(), 
                Arrays.<TypeReference<?>>asList(new TypeReference<Utf8String>() {}));
        return executeRemoteCallSingleValueReturn(function, String.class);
    }

And transferFrom() for ERC20

    public RemoteCall<TransactionReceipt> transferFrom(String _from, String _to, BigInteger _value) {
        final Function function = new Function(
                FUNC_TRANSFERFROM, 
                Arrays.<Type>asList(new org.web3j.abi.datatypes.Address(_from), 
                new org.web3j.abi.datatypes.Address(_to), 
                new org.web3j.abi.datatypes.generated.Uint256(_value)), 
                Collections.<TypeReference<?>>emptyList());
        return executeRemoteCallTransaction(function);
    }

When called it will execute a function executeRemoteCallXXXXX(function).

To construct a dynamic class you have to construct function which you pass the name of the function to invoke, a list with input parameters and a list with output parameters. See here https://github.com/web3j/web3j/blob/a0ece8b8fb76397c24592cc9d59578cdabbf751c/abi/src/main/java/org/web3j/abi/datatypes/Function.java#L17-L22.

public Function(String name, List<Type> inputParameters,
                    List<TypeReference<?>> outputParameters) {
        this.name = name;
        this.inputParameters = inputParameters;
        this.outputParameters = convert(outputParameters);
}
