To reproduce the error:

1. Clone this repository.
2. Checkout the token-template branch

3. Run the below test using ./gradlew test

   public class FlowTests {
   private final MockNetwork network = new MockNetwork(ImmutableList.of(
           "com.template.contracts", "com.template.flows",
           "com.r3.corda.lib.tokens.money",
           "com.r3.corda.lib.tokens.contracts",
           "com.r3.corda.lib.tokens.workflows",
           "com.r3.corda.lib.tokens.testing"));
   private final StartedMockNode exchangeNode = network.createNode();
   private final Party exchange = exchangeNode.getInfo().getLegalIdentities().get(0);
   
   @Before
   public void setup() {
       network.runNetwork();
   }
   
   @After
   public void tearDown() {
       network.stopNodes();
   }
   
   @Test
   public void dummyTest() throws ExecutionException, InterruptedException {
       ExampleFlowWithFixedToken issueFlow = new ExampleFlowWithFixedToken("USD", 1000L, exchange);
       Future<SignedTransaction> future = exchangeNode.startFlow(issueFlow);
       network.runNetwork();
       SignedTransaction tx = future.get();
       System.out.print(tx);
   }
   }
