> Can you explain how this NPE exception happens? When a worker object is initialized, pushServer and fetchServer will be created first and provide services. When receiving a request, the server determines whether the handler is ready by checking registered. In the original implementation, although registered is assigned a value, the handler may still not be ready. The code after registered is assigned a value may not have been executed completely. Generally, the more EventLoopGroup threads there are, the greater the probability of this occurrence. In this PR, we place the assignment of registered at the end, which can avoid this situation. -- This is an automated message from the Apache Git Service.
