Ⅰ. Issue Description

使用seata-all 1.6.1作为客户端依赖，伪代码如下：

public class Test{

  private static String applicationId="abcd";
    private static String transactionServiceGroup="my_test_tx_group";
    static{
        TMClient.init(applicationId, transactionServiceGroup);
        RMClient.init(applicationId, transactionServiceGroup);
    }
    private static final TransactionalTemplate transactionalTempl = new TransactionalTemplate();

    public static void test() throws Throwable{
        try {
            transactionalTemplate.execute(new TransactionalExecutor() {
                @Override
                public Object execute() throws Throwable {

                    throw new RuntimeException();
                }

                @Override
                public TransactionInfo getTransactionInfo() {

                    TransactionInfo transactionInfo = new TransactionInfo();
                    transactionInfo.setTimeOut(180000);
                    transactionInfo.setName("default");
                    transactionInfo.setPropagation(Propagation.REQUIRED);

                    Set<RollbackRule> rollbackRules = new LinkedHashSet<>();
                    rollbackRules.add(new RollbackRule(Throwable.class));

                    transactionInfo.setRollbackRules(rollbackRules);
                    return transactionInfo;
                }
            });
        }catch (Throwable e){
            e.printStackTrace();
        }

        int i=0; //在此处添加断点，debug让程序跑到断点处停下来，会出现两次回滚 Rollback global transaction successfully

    }

    public static void main(String[] args) throws Throwable{
        test();
    }

}

上面图片里出现两次全局回滚，并且数据库global_table表里的相应的记录很长时间才删除！

registry.conf文件内如如下：

registry {
  # file 、nacos 、eureka、redis、zk
  type = "nacos"

  nacos {
      application="seata-server"
      serverAddr="192.168.137.199:8848"
      namespace=""
      cluster="default"
      group="SEATA_GROUP"
      username="nacos"
      password="nacos"
  }
}

config {
  # file、nacos 、apollo、zk
  type = "file"
  file {
    name = "file.conf"
  }
}

//file.conf文件内容如下
