[GitHub] [rocketmq] huskyui opened a new issue, #4421: 有段try-catch代码没理解
huskyui opened a new issue, #4421:
URL: https://github.com/apache/rocketmq/issues/4421
```
public void deleteTopic(final String topic) {
try {
try {
this.lock.writeLock().lockInterruptibly();
this.topicQueueTable.remove(topic);
} finally {
this.lock.writeLock().unlock();
}
} catch (Exception e) {
log.error("deleteTopic Exception", e);
}
}
```
最里面是try finally我理解，外面这一层的try catch我不理解它的意义是啥
