为什么拿到旧链接一定会是被end过的？假设connection.setautocommit(false) 开启事务，然后有一个耗时很长的sql，或者业务逻辑，此时TC触发这个全局事务的超时回滚，进行下发的该RM，从RM拿到被hold的连接进行rollback，由于没有end只会失败，怎么会成功呢？ Why would obtaining the old connection necessarily mean end() has already been called? Suppose you call connection.setAutoCommit(false) to start a transaction, and then a long-running SQL statement or business logic is running. If the TC triggers a global transaction timeout and issues a rollback to the RM, the RM will take the held connection and call rollback. Without calling end() first the rollback would fail — how could it possibly succeed? -- This is an automated message from the Apache Git Service.
