String sql = "update client_log set branch_status = ? where transactional_id = ? and branch_id = ?";
ps = connection.prepareStatement(sql);
ps.setInt(1, status);
ps.setString(2, transactionalId);
ps.setString(3, branchId);
ps.execute();
调用ps.execute()时，报这个异常，找了很久，不知道什么原因

Start at DruidPooledConnection.java:726 and follow the transactionRecord calls from DruidPooledStatement.java:285 and DruidPooledPreparedStatement.java:491. Reproduce the supplied prepareStatement and ps.execute() sequence with the reporter's database and configuration, then identify the missing state and add a regression test showing that the call no longer raises a NullPointerException.
