> There is an entity Node2 which is using an identity class.
> It is introduced in an unit test attached to related issue OPENJPA-2144.
> I have made two sequential queries to Node2 at the same transaction, but different query objects in order to use prepared SQL query Cache.
> JPQL: SELECT p FROM Node2 p WHERE p.parent = :parent
> Not cached query works fine and returns not empty list:
> 302884 test TRACE [main] openjpa.Runtime - Query "SELECT p FROM Node2 p WHERE p.parent = :parent" is cached."
> 302884 test TRACE [main] openjpa.Query - Executing query: [SELECT p FROM Node2 p WHERE p.parent = :parent] with parameters: {parent=1351::1::2}
> 302962 test TRACE [main] openjpa.jdbc.SQL - <t 5142872, conn 30621423> executing prepstmnt 21961831 SELECT t0.district, t0.id, t0.region, t0.version, t0.data, t0.PARENT_ID FROM NODE2 t0 WHERE (t0.PARENT_ID = ? AND t0.region = ? AND t0.district = ?) [params=(long) 1351, (int) 1, (int) 2]
> Sequential cached query returns empty list:
> 346242 test TRACE [main] openjpa.Query - Executing query: [SELECT p FROM Node2 p WHERE p.parent = :parent] with parameters: {0=1, 1=1, 2=2}
> 346242 test TRACE [main] openjpa.jdbc.SQL - <t 5142872, conn 30621423> executing prepstmnt 13122813 SELECT t0.district, t0.id, t0.region, t0.version, t0.data, t0.PARENT_ID FROM NODE2 t0 WHERE (t0.PARENT_ID = ? AND t0.region = ? AND t0.district = ?) [params=(int) 1, (int) 1, (int) 2]
> You can see that wrong paraments were passed into the cached generated raw SQL in the second query!
> That is the problem, we have wrong query result.
