The JPA inheritance type is Inheritance.Joined.<br> The test uses a JPA query that will match an attribute on the base class or on the child class.<br> The test goes like this<br> Begin transaction<br> Create a child entity that will match the query on the base class.<br> Execute the query and confirm 1 record is returned (this works on hibernate 4.1.1 and 5.3.6)<br> Create a second child entity that will match the query on the child class<br> Execute the query and confirm that 2 records are returned (this works on hibernate 4.1.1 and fails on hibernate 5.3.6)<br> End Transaction<br> Tracing the SQL being executed against the database I see the following:<br> Insert into base table<br> Select<br> Insert into child table<br> Insert into base table<br> Select<br> Insert into child table</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0">So the reason that the test is failing appears to be because the insert into the child table is happening after the select statement so the select doesn't match it.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0">My understanding is that all inserts should be executed prior to a select but this doesn't appear to be the case for the child table i.e. the entity has only partially been inserted before the select query is executed.<br> I tried adding a manual em flush prior to executing the query and this had no effect.<br> I have looked for hibernate properties that might influence this behavior and not been successful hence reporting this as a bug.</p> </td>
