Describe the Bug

AuthorizationFactory

public static AuthorizationStrategy getStrategy(AuthConfig config, Supplier<?> metadataService) {
try {
Class<? extends AuthorizationStrategy> clazz = StatelessAuthorizationStrategy.class;
if (StringUtils.isNotBlank(config.getAuthenticationStrategy())) { // wrong
clazz = (Class<? extends AuthorizationStrategy>) Class.forName(config.getAuthorizationStrategy());
}
return clazz.getDeclaredConstructor(AuthConfig.class, Supplier.class).newInstance(config, metadataService);
} catch (Exception e) {
throw new RuntimeException(e);
}
}

Steps to Reproduce

broker.conf

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

authenticationEnabled = true
authenticationProvider = org.apache.rocketmq.auth.authentication.provider.DefaultAuthenticationProvider
initAuthenticationUser = {"username":"rocketmq","password":"12345678"}
innerClientAuthenticationCredentials = {"accessKey":"rocketmq","secretKey":"12345678"}
authenticationMetadataProvider = org.apache.rocketmq.auth.authentication.provider.LocalAuthenticationMetadataProvider
authenticationStrategy = org.apache.rocketmq.auth.authentication.strategy.StatefulAuthenticationStrategy
