PreparedQuery gives wrong result if query has subquery and parameters are used 
in both main select and subselect

                 Key: OPENJPA-1584
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1584
             Project: OpenJPA
          Issue Type: Bug
          Components: performance
    Affects Versions: 2.0.0
            Reporter: Catalina Wei
            Assignee: Catalina Wei


a back-to-back of the following JPQL query providing different set of parameter 
values, 
the second execution gives wrong answer.

 "select o from OrderJPA o where o.OrderId in (select max(o1.OrderId) from 
OrderJPA o1 where ((o1.CustomerId = :customerId) and (o1.DistrictId = 
:districtId) and (o1.WarehouseId = :warehouseId))) and (o.CustomerId = 
:customerId) and (o.DistrictId = :districtId) and (o.WarehouseId = 
:warehouseId)"

SQL trace shown the first time query execution, let say customerId=339, 
districtId=3, warehouseId=23, then query returns 1 row:

the SQL trace looked fine:

[3/16/10 17:40:36:831 CDT] 00000045 OpenJPA       3   openjpa.jdbc.SQL: Trace: 
<t 241897067, conn 1981117973> executing prepstmnt 1547852866 SELECT t0.O_D_ID, 
t0.O_ID, t0.O_W_ID, t0.VERSION, t0.O_ALL_LOCAL, t0.O_CARRIER_ID, t0.O_C_ID, 
t0.O_ENTRY_D, t0.O_OL_CNT FROM ORDERS t0 WHERE (t0.O_ID IN (SELECT MAX(t1.O_ID) 
FROM ORDERS t1 WHERE (t1.O_C_ID = ? AND t1.O_D_ID = ? AND t1.O_W_ID = ?) ) AND 
t0.O_C_ID = ? AND t0.O_D_ID = ? AND t0.O_W_ID = ?)  optimize for 1 row 
[params=(short) 339, (short) 3, (short) 23, (short) 339, (short) 3, (short) 23]

On the next execution of the same JPQL, the PreparedQueryImpl (which is cached 
before) gets reused.
In processing user provided parameters, for example, customerId=2967, 
districtId=5, warehouseId=22,
It is observed that the parameter values are incorrect: the last 3 values were 
incorrectly copied from the previously cached version.
