Buggy source:
public Payment createPayment(final UUID accountId,@Nullable final UUID paymentMethodId,final PaymentTransaction paymentTransaction,@Nullable List<String> controlPluginNames,final Map<String,String> pluginProperties,final RequestOptions options) throws KillBillClientException {
  Preconditions.checkNotNull(accountId,"String_Node_Str");
  Preconditions.checkNotNull(paymentTransaction.getTransactionType(),"String_Node_Str");
  Preconditions.checkArgument("String_Node_Str".equals(paymentTransaction.getTransactionType()) || "String_Node_Str".equals(paymentTransaction.getTransactionType()) || "String_Node_Str".equals(paymentTransaction.getTransactionType()),"String_Node_Str" + paymentTransaction.getTransactionType());
  Preconditions.checkNotNull(paymentTransaction.getAmount(),"String_Node_Str");
  Preconditions.checkNotNull(paymentTransaction.getCurrency(),"String_Node_Str");
  final String uri=JaxrsResource.ACCOUNTS_PATH + "String_Node_Str" + accountId+ "String_Node_Str"+ JaxrsResource.PAYMENTS;
  final Multimap<String,String> params=HashMultimap.<String,String>create();
  if (paymentMethodId != null) {
    params.put("String_Node_Str",paymentMethodId.toString());
  }
  if (controlPluginNames != null) {
    params.putAll(KillBillHttpClient.CONTROL_PLUGIN_NAME,controlPluginNames);
  }
  storePluginPropertiesAsParams(pluginProperties,params);
  final RequestOptions requestOptions=options.extend().withQueryParams(params).withFollowLocation(true).build();
  return httpClient.doPost(uri,paymentTransaction,Payment.class,requestOptions);
}

Fixed version (ground truth):

  Preconditions.checkNotNull(paymentTransaction.getAmount(),"String_Node_Str");
  Preconditions.checkNotNull(paymentTransaction.getCurrency(),"String_Node_Str");
  final String uri=JaxrsResource.ACCOUNTS_PATH + "String_Node_Str" + accountId+ "String_Node_Str"+ JaxrsResource.PAYMENTS;
  final Multimap<String,String> params=HashMultimap.create(inputOptions.getQueryParams());
  if (paymentMethodId != null) {
    params.put("String_Node_Str",paymentMethodId.toString());
  }

    params.putAll(KillBillHttpClient.CONTROL_PLUGIN_NAME,controlPluginNames);
