Lars Heyden commented on ANN-731:
---------------------------------

Ok, I have no insight when "synthetic properties for non-PK-references" was introduced. What I can say it is in use in 3.3.1.GA so find out yourself.

- map an entity B with a non-PK to-one association to an entity A.
- create a SqlResultSetMapping for A.
- query for an instance of A with a native query using the SqlResultSetMapping.

You will get an exception from the JDBC driver telling that a column was requested that wasn't specified in the query. In a debugger this goes back to code that tries to get a value for an internally generated property of A named "B_A" or something like that.

> The generation of synthetic properties for non-PK-references introduces with ANN-548 makes it impossible to use @SqlResultSetMapping. When doing a native query Hibernate tries to read values for these properties out of columns (column aliases) that do not exist.
