CLONE -Hibernate 3.1 throws a Null pointer exception when using a regular HQL query to retrieve a persistent instance using a select statement with the classes being packaged in a JAR.

Key: HB-1565
URL: http://opensource.atlassian.com/projects/hibernate/browse/HB-1565
Project: Hibernate2
Type: Bug
Versions: 3.0 rc 1
Environment: Hibernate 3.1, Pointbase
Reporter: udd
I have a web application wherein I make a simple query - select conviction from Conviction conviction with a custom where clause. When there is no matching data, the exception as mentioned below is not thrown but when there is a matching row found, the exception is thrown back. I believe this bug relates to the bug in Hibernate when the classes are packaged in a signed JAR. The only reason I am getting this error is because all my classes are packaged in a JAR file and the same query works when the class is locally used on a command line.
Hibernate: select conviction0_.CONVICTION_ID as CONVICTION1_8_, conviction0_.OFFENSE_COUNTRY as OFFE

[Hibernate-JIRA] Commented: (HHH-1846) Collection of subclassed objects includes objects with wrong discriminator type
by Mathieu Veron (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1846?page=c... ]
Mathieu Veron commented on HHH-1846:
------------------------------------
We have the same issue on Hibernate 3.0.5, MySql 4.1.9,
on a very similar mapping,
with a one-to-many default fetch.
In our case a where condition is possible on the set, but is not clean imho.

> This isn't the actual way we found this bug - this also affects caching: we had the collection cached, and when an individual element of the collection expires from the cache, Hibernate tries to reload it by id and descriminator, and can't find elements that shouldn't have been loaded in the first place, throwing, for example, this trace:

[Hibernate-JIRA] Commented: (HHH-572) Repeated columns rejected in a collection of composite elements
by greg jablonski (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-572?page=co... ]
greg jablonski commented on HHH-572:
------------------------------------
Is there a workaround for the case where you want the many-to-one to be the derived association? I'm trying to do this because my many-to-one is mapped with not-found="ignore", and the property mapping to the same column is that foreign key, and I want to have access to the foreign key value regardless of whether the association is null or not, and a formula won't let me save that property if the many-to-one is null.
What I want to do is this:
<set name="siblings" table="SIBLINGS">
<key column="child_id" />
<composite-element class="Child">
<property name="foo" column="foo">
<property name="siblingId" column="sibling_id" />
<many-to-one name="sibling" column="sibling_id" class="Child" update="false" insert="false" not-found="ignore" />
</composite-element>
</set>
(I realize this looks a little strange, but SIBLING is really a direction-specific many-to-many join table augmented with "foo" in the example case.) Thanks.
