Review comment:
Would it be cleaner by using `InvocationHander` to inject these
`isLeader()` check ?
```
StateManager pipelineStateManager = (StateManager) Proxy.newProxyInstance(
null,
new Class<?>[] {StateManager.class},
(proxy, method, args) -> {
if (method.getName().equals("xxx")) {
// do is leader check;
// throw exception if needed;
}
return method.invoke(args);
});
```
You may use `hashmap` or `annotation` to speed up the method name check.
Just a recommendation.
