### Pre-check - [x] I am sure that all the content I provide is in English. ### Search before asking - [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar feature requirement. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Descriptions I'm upgrading dubbo from 3.2.x to 3.3.x, to pick a best version to use * nacos+zookeeper * double registry * one port for triple+dubbo protocol (the 3.3.x support HTTP payload to call triple port) before we upgrade, we test compatibility with zookeeper + curator + dubbo To take advantages of Service Discovery, we need curator-x-discovery, but our zookeeper server version is pretty low: 3.4.12, so we cannot use curator5, but we test that curator version 4.2.0 works with dubbo 3.2.4 pretty well for a long time, although dubbo need `dubbo-remoting-zookeeper-curator5` ``` <dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-x-discovery</artifactId> <version>4.2.0</version> </dependency> ``` When uprade dubbo to 3.3.14, we get: ``` WARN [main] o.s.b.w.s.c.AnnotationConfigServletWebServerApplicationContext Exception encountered during context initialization - cancelling refresh attempt: java.lang.NoSuchMethodError: 'org.apache.curator.framework.CuratorFrameworkFactory$Builder org.apache.curator.framework.CuratorFrameworkFactory$Builder.ensembleTracker(boolean)' ``` When upgrade dubbo to lastet: 3.3.5, we get errors about zookeeper connection problem even upgrade zookeeper to 3.9.4. (impossible connect to zk server 3.4), to search the solution, some people give advices such as downgrade to jdk8 (not acceptable for us) 1. Unable to canonicalize address localhost/<unresolved>:7181 because it's not resolvable 2. https://issues.apache.org/jira/browse/ZOOKEEPER-3779 TLDR: pick a best dubbo version to run Dubbo 3.3.x with zookeeper 3.4.12, that is dubbo 3.2.13 (change curator version)，see the breaking changes with: https://github.com/apache/dubbo/blob/a7b641f51e7166051c3006b3cc6f2e8a2dfd64f3/dubbo-remoting/dubbo-remoting-zookeeper-curator5/src/main/java/org/apache/dubbo/remoting/zookeeper/curator5/Curator5ZookeeperClient.java#L78 ### Related issues _No response_ ### Are you willing to submit a pull request to fix on your own? - [x] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
