[GitHub] [rocketmq] XiaoyiPeng opened a new issue #4060: The list of exception declarations in the send method signature cannot contain all exceptions that may be encountered when sending a message
XiaoyiPeng opened a new issue #4060:
URL: https://github.com/apache/rocketmq/issues/4060
**BUG REPORT**
1. Please describe the issue you observed:
When I send messages using `TransactionMQProducer`, I encounter a `java.lang.IllegalStateException` which is not in the list of exception declarations in the send method signature
```java
DefaultMQProducer#send(Message msg)
throws MQClientException, RemotingException,
MQBrokerException, InterruptedException
```
as below shown:
It's due to method `MQClientInstance#updateTopicRouteInfoFromNameServer`, when it catch `RemotingException`, a `IllegalStateException` is rethowed.
as shown below:
It would be better to throw the caught `RemotingException` here.
In addition, many methods in **client API** , if they interact with the broker side, It would be better to declaring `RemotingException` in their method signatures, eg:
```java
long maxOffset(final MessageQueue mq) throws MQClientException;
```
2. Please tell us about your environment:
OS：Windows10
branch: develop
