Spring with Google Spanner raise error

Question

I am trying to connect to Google Spanner with java using spring boot. I wan't to read something from database and send it with web socket. Currently I have:

@Configuration
@EnableScheduling
@SpringBootApplication
@EnableWebSocketMessageBroker
public class SpannerServiceApplication extends AbstractWebSocketMessageBrokerConfigurer {

    public static void main(String[] args) {
        SpringApplication.run(SpannerServiceApplication.class, args);
    }

    @Bean
    public DatabaseClient spannerDatabase(){
        SpannerOptions options = SpannerOptions.newBuilder().setProjectId("p").build();
        Spanner spanner = options.getService();
        return spanner.getDatabaseClient(DatabaseId.of(options.getProjectId(), "test123", "test"));
    }

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/backend").setAllowedOrigins("*").withSockJS();
    }
}

and pom:

Switch to Jetty and netty-tcnative-boringssl-static did not help. My error:

Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.0.BUILD-SNAPSHOT:run (default-cli) on project SpannerService: An exception occurred while running. null: InvocationTargetException: Error creating bean with name 'spannerDataba

Spring boot 2.0, Java 1.8, Tomcat 8.5.16 What's wrong? Thank you!

So what I did to make it work: I upgraded java version from update 122 to 144(newest), changed pom into this:
