Rate limit does not work when working with other bundles

[wzhongyuan]

I have following bundle setup for my application, it seems that if we have other bundle added into the BootStrap, the rate limit is not working and would throw NullPointerException

 LOGGER.info("starting to do initialization...");
    LOGGER.info("adding ratelimit factory bundle");
    RequestRateLimiterFactory factory = new InMemoryRateLimiterFactory();
    bootstrap.addBundle(new RateLimitBundle(factory));
    LOGGER.info("added ratelimit factory bundle");
    guiceBundle = GuiceBundle.<KrylovMasterConfiguration>newBuilder()
        .addModule(new ConfigModule())
        .addModule(new ResourceModule())
        .addModule(new CoreServiceModule())
        .addModule(new AuthModule())
        // .addModule(new CommonModule()) // Needed for workflow and workspace, do not remove
        //.addModule(new ZookeeperClientModule()) //Needed for workflow and workspace, do not remove
        .addModule(new DefaultServerModule())
        .addModule(new DefaultWorkspaceModule())
        .addModule(new ExtensionModule())
        .addModule(new RateLimitModule())
        //.enableAutoConfig(getClass().getPackage().getName())  // disable this to prevent accidental registration.
        .setConfigClass(KrylovMasterConfiguration.class)
        .build();
// if we add this line of code. rate limit won't work
    bootstrap.addBundle(guiceBundle);

the exception is
