2. OS type and version: Mac
3. Java version: 17
4. bigtable version(s): Docker BigTable

Steps to reproduce

1. Start gcloud BigTable emulator in local Docker.
2. Run the basic Read example - https://github.com/googleapis/java-bigtable/blob/main/samples/snippets/src/main/java/com/example/bigtable/Reads.java

                 BigtableTableAdminClient.create(projectId, instanceId)) {
            CreateTableRequest createTableRequest =
                CreateTableRequest.of(tableId)
                                  .addFamily(COLUMN_FAMILY_NAME_STATS)
                                  .addFamily(COLUMN_FAMILY_NAME_PLAN);
            adminClient.createTable(createTableRequest);
        } catch (IOException e) {
            System.out.println("Error during createTable: \n" + e.toString());
            throw (e);
        }
