EmbeddedCassandraServerHelper returning that keyspace exists when it doesn't

Question

I check for the keyspace, System.out.println(cluster.getMetadata().getKeyspace(finalKeyspace));, which returns null. However, when I try to create the keyspace it returns keyspace 'library' already exists from when I first ran the program.

public static void setupEmbeddedCassandra(String cqlFile, String keyspaceName)
      throws IOException, TTransportException, InterruptedException {
    synchronized (lock) {
      if (finalKeyspace == null) {
        System.out.println(CLASS_NAME + " Setting up local embedded cassandra environment");
        EmbeddedCassandraServerHelper.startEmbeddedCassandra();
        
        int embeddedCassandraPort = EmbeddedCassandraServerHelper.getNativeTransportPort();
        System.setProperty("embeddedCassandraPort", String.valueOf(embeddedCassandraPort));
        cluster =
            (new Cluster.Builder())
                .addContactPoints(new String[] {"localhost"})
                .withPort(embeddedCassandraPort)
                .build();
        session = cluster.connect();
        cluster.getConfiguration();
        System.out.println(cluster.getMetadata().getKeyspace("library"));
        CQLDataLoader dataLoader = new CQLDataLoader(session);
        System.out.println(cluster.getMetadata().getKeyspace("library"));
        dataLoader.load(new ClassPathCQLDataSet(cqlFile, true, keyspaceName));
        System.out.println(
            CLASS_NAME
                + " Embedded Server started on port "
                + EmbeddedCassandraServerHelper.getNativeTransportPort());
      }
      finalKeyspace = keyspaceName;
      System.out.println("here " + cluster.getMetadata().getKeyspace(finalKeyspace));
    }
  }

I also run a method at the end of each test that drops each keyspace. When i check for the existing keyspace after running the drop method, it returns null for the "library" keyspace as expected.
