io.github.bucket4j.grid.hazelcast.Hazelcast is not registered

[lkcverma9]

Hello,
We are using bucket4j for the rate limit in our application. It works on the current application with the following version.

Spring boot: 2.7.2
Hazelcast version: 5.1.2
java: 1.8 :
bucket4j-core: 6.2.0
bucket4j-hazelcast: 6.2.0
bucket4j-cache: 6.2.0

Now We have upgraded our application from Java 1.8 to 17. In this process, we are using the following version.

Spring boot: 2.7.2
Hazelcast version: 5.1.2
java: 17 :
bucket4j-core: 6.2.0
bucket4j-hazelcast: 6.2.0
bucket4j-cache: 6.2.0
**Sometimes applications work fine but sometimes io.github.bucket4j.grid.hazelcast.Hazelcast is not registered.

Please suggest to us what we can do to resolve this issue.**

[vladimir-bukhtoyarov]

Looks that java.util.ServiceLoader.load behaves in different way after migration to java-17, as result this file is not discovered.

Bucket4j does not use ServiceLoader since 7.0.0, so I recommend to migrate to fresh Bucket4j.

If upgrading Bucket4j version is not possible, just rewrite your code to direct usage of class io.github.bucket4j.grid.hazelcast.Hazelcast:

new Hazelcast()
// instead of Bucket4j.extension(Haszelcast.class)

Thanx for your suggestion. now I am using the latest buckt4j version and update the code and now it's working fine.
