I am trying to use the bucket4j with Hazelcast, but the follow exception is throw:

My code is just like this:

public class Bucket4jHazelcast {

    /**
     * @param args
     */
    public static void main(String[] args) {
        ClientConfig clientConfig = new ClientConfig();
        clientConfig.getNetworkConfig().addAddress("localhost");
        HazelcastInstance instance = HazelcastClient.newHazelcastClient(clientConfig);

        Bucket bucket = Bucket4j.extension(Hazelcast.class).builder()//
                .addLimit(Bandwidth.simple(10, Duration.ofMinutes(1)))//
                .build(instance.getMap("test"), "test", RecoveryStrategy.RECONSTRUCT);

        bucket.tryConsume(1);
    }

}

Can you help me?

I never seen before the HazelcastInstance, looks like it has been introduced within Hazelcast 3.9. Based on common sense I suppose that you are trying to connect as ligh-weight client to the another hazelcast server node. If I am right then check that following jars present in classpath of the Hazelcast server node:

• bucket4j-core
• bucket4j-jcache
• bucket4j-hazelcast

These jars should present on both client and server nodes.

Thanks a lot, it works!
