### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version pulsar version : 2.11.0 java version : 1.8 ### Minimal reproduce step My purpose is to use flink to consume the topic data set in pulsar, because our cluster uses kerberos for authentication, so when I use ： configuration.set(PulsarOptions.PULSAR_AUTH_PLUGIN_CLASS_NAME, org.apache.pulsar.client.impl.auth.AuthenticationSasl .class.getName());, a compilation error occurs: Cannot access org.apache.pulsar.client.impl.auth.AuthenticationSasl - Stack Overflow Bad class file: /C:/Users/admin/.m2/repository/org/apache/pulsar/pulsar-client-auth-sasl/2.11.0/pulsar-client-auth-sasl-2.11.0.jar! /org/apache/pulsar/client/impl/auth/AuthenticationSasl.class Class file has wrong version 61.0, should be 52.0 Please delete the file or make sure the file is in the correct classpath subdirectory. But when I use the 2.10.0 version of pulsar, it will be compiled normally, so I think that the compilation of pulsar2.11 version is carried out using java17, and it is not available in pulsar-client as the official website said compile with java8 ### What did you expect to see? I think in version 2.11 of pulsar I can still use java8 to compile ### What did you see instead? Cannot access org.apache.pulsar.client.impl.auth.AuthenticationSasl - Stack Overflow Bad class file: /C:/Users/admin/.m2/repository/org/apache/pulsar/pulsar-client-auth-sasl/2.11.0/pulsar-client-auth-sasl-2.11.0.jar! /org/apache/pulsar/client/impl/auth/AuthenticationSasl.class Class file has wrong version 61.0, should be 52.0 Please delete the file or make sure the file is in the correct classpath subdirectory. ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
