Hi All

There is a NPE was thrown out from hibernate source code, the NPE is a intermittent issue in my test environment, if it didn't happen during 4 hours, it will don't happen any more. Below is my source code:

Code:

SQLQuery query = session.createSQLQuery("update process_instance set step_id=?, status=?, cost=?, time_ended=? where process_id=?");
query.setString(0, inst.getStepId());
query.setInteger(1, inst.getStatus());
query.setLong(2, inst.getCost());
query.setTimestamp(3, inst.getTimeEnded());
query.setLong(4, inst.getProcessId());
                            
int exist = query.executeUpdate();

Below is the statck trace:

could you show enough code to try reproducing the problem?
Ideally you should make a unit test and open an issue on JIRA, assuming it's not caused by an error in your code/model
