Query with Composite Primary Key parameter crashes when query cache is on
-------------------------------------------------------------------------
Key: HHH-4459
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4459
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.3.2
Environment: Hibernate Core 3.3.2.GA, MySQL and H2
Reporter: Karol Bienkowski
I have an entity with a composite identifier (primary key) annotated with EmbeddedId:
@Embeddable
public class CompositeKey implements Serializable {
(...)
}
@Entity
public class EntityWithCompositeKey {
@EmbeddedId
public CompositeKey pk;
(...)
}
When executing query ...
FROM EntityWithCompositeKey e WHERE e.pk = :pk
... where ":pk" is bound to an instance of CompositeKey ...
query.setParamter("pk", new CompositeKey(..))
... I get the following exception:

It used to work on 3.3.1.GA but fails in 3.3.2.GA. Turning off query cache works.
The direct reason for the error is that TypedValue.value is an Object[] but
ComponentType.getHashCode() expects TypedValue.value to be of CompositeKey type.
I'll attach the working test case replicating the issue in a moment.

Alain Mahier commented on HHH-4459:
-----------------------------------
The problem seems coming from the initialization of the QueryKey.
The query key is created with all namedParameters disassembled by Type.disassemble. All
those disassembled named parameter values are typed with the original Type (ComponentType,
CustomType ...) and when QueryKey computes the hashCode on namedParameters, the original
Type.hashCode method is used on an array of Object values instead of the original value
(before disassemble).

---------------------------------------
This occurs with ComponentType as well as CompositeKey (perhaps not too surprisingly :)
See the thread in the Hibernate Users Community bbd "Error upgrading to hibernate
3.3.2 :IllegalArgumentException" thread started June 26, 2009 for other examples and
commentary.

It used to work on 3.3.1.GA but fails in 3.3.2.GA. Turning off query cache works.
The direct reason for the error is that TypedValue.value is an Object[] but
ComponentType.getHashCode() expects TypedValue.value to be of CompositeKey type.
I'll attach the working test case replicating the issue in a moment.
