Null pointer exception on org.hibernate.type.AbstractType.getHashCode(AbstractType.java:112)
--------------------------------------------------------------------------------------------
Key: HHH-3441
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3441
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.5
Environment: Hibernate 3.25., Oracle 10g, Spring 2.5.5
Reporter: DEROUET
Priority: Blocker
The issue concerns a problem already signaled in different forums, and I decided to report it in JIRA, because many people have this same problem and after days and days of work around, the solutions possibles are heavy or dangerous for a database integrity (for example remove a non-nullability constraint...).
Here it is the problem a previous forum participant had perfectly summarized (see http://opensource.atlassian.com/projects/hibernate/browse/HHH-2326):
A null pointer exception is thrown when:
a) we have a composite key with one of the attributes of the key being an FK to another persistent class.
b) The other persistent class has an ID field whose value is being generated.
c) The instance of the other persistent class is transient (does not yet have an ID)
We do not get the null pointer if we explicitly set the ID (generator=assigned)
Here it is the failure trace:

[Hibernate-JIRA] Created: (HHH-3464) SimpleExpression.ignoreCase uses SQL server lowercase function for left part and JAVA lowercase function for right part of expression

SimpleExpression.ignoreCase uses SQL server lowercase function for left part and JAVA lowercase function for right part of expression
-------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-3464
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3464
Project: Hibernate3
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.2.6
Environment: tried with PostgreSQL
Reporter: Vitaliy Tymchyshyn
Priority: Minor
When using SimpleExpression.ignoreCase (e.g. Restrictions.eq().ignoreCase, hibernate makes 'lower(field)=?' SQL expression, passing lowercased strings to '?' parameter. This may produce unpredictable results depending on Database server lower implementation and current JAVA locale (see JDK javadoc).
For example, I've tried with '\u0130' character as in JDK JavaDoc.
Postgresql produces:
unhappy=> select lower('İ');
lower
-------
i̇
(1 row)
unhappy=> select char_length(lower('İ'));
char_length
-------------
2
(1 row)
While Java with default locale produces single-character 'i̇'. Of course the restriction will not work - it can not find 'İ' in database.
I'd recommend to use 'lower(field)=lower(?)' to use same lower casing function for both parts of expression.

Basically, hibernate allows to define <cache usage="transactional"/> inside the subclass mapping, i.e.
<subclass name="SubClass" extends="BaseClass" discriminator-value="xxx">
<bag name="subClassLinks" lazy="false" inverse="true" batch-size="100">
<cache usage="transactional" region="xxx"/>
<key column="xxx" not-null="true"/>
<one-to-many class="xxx"/>
</bag>
<join table="xxx">
</join>
</subclass>
but it's not allowed to do the same using <collection-cache collection="subClass.myCollection" region="xxx" usage="transactional"/>.
It throws:
Exception in thread "main" org.hibernate.MappingException: Cannot cache an unknown collection: subClass.myCollection

[Hibernate-JIRA] Created: (HHH-2851) ParameterTranslationsImpl fails to correctly determine parameter type

ParameterTranslationsImpl fails to correctly determine parameter type
---------------------------------------------------------------------
Key: HHH-2851
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2851
Project: Hibernate3
Issue Type: Bug
Components: query-hql
Affects Versions: 3.2.5
Reporter: Alex Savitsky
Priority: Minor
For the conditions in the form "(:param IS NULL OR alias.someField = :param)", the HQL parses would not correctly determine the type of param, unless the conditions are swapped like "(alias.someField = :param OR :param IS NULL)". The reason is that NamedParamTempHolder classes are created for all parameter entries, in the order they appear in the query. The first occurrence (:param IS NULL) would have its expectedType set to null, and the second occurrence would use the param holder created by the first occurrence, without checking whether it can improve it in any way (which it can - the expectedType for second occurrence is correctly determined to be Long).
Proposed fix would be to check for this particular condition, enhancing paramHolder if possible, with new information:
old code:
if ( paramHolder == null ) {
paramHolder = new NamedParamTempHolder();
paramHolder.name = namedSpec.getName();
paramHolder.type = namedSpec.getExpectedType();
namedParameterMap.put( namedSpec.getName(), paramHolder );
}
new code:
if ( paramHolder == null ) {
paramHolder = new NamedParamTempHolder();
paramHolder.name = namedSpec.getName();
paramHolder.type = namedSpec.getExpectedType();
namedParameterMap.put( namedSpec.getName(), paramHolder );
+ } else if (paramHolder.getExpectedType() == null && namedSpec.getExpectedType() != null) {
+ paramHolder.type = namedSpec.getExpectedType();
}

The above mapping should use the "priority" field to the ordering.
SQL that is produced is :
select criteria0_.RoutingRuleId as RoutingR1_1_, criteria0_.CriteriaComponentId as Criteria2_1_,
criteria0_.ListIndex as ListIndex1_,
routingcri1_.id as id73_0_,
routingcri1_.creationDate as creation3_73_0_,
routingcri1_.description as descript4_73_0_,
routingcri1_.lastModificationDate as lastModi5_73_0_,
routingcri1_.name as name73_0_,
routingcri1_.predefined as predefined73_0_,
routingcri1_.status as status73_0_,
routingcri1_.priority as priority73_0_,
routingcri1_.visible as visible73_0_,
routingcri1_.matcher_id as matcher25_73_0_,
routingcri1_.criterion_id as criterion27_73_0_,
routingcri1_.location_id aslocation26_73_0_,
routingcri1_.RoutingComponentType as RoutingC1_73_0_
from odp_rulecriteriajoin criteria0_
left outer join odp_routingcomponent as routingcri1_ on criteria0_.CriteriaComponentId=routingcri1_.id
where criteria0_.RoutingRuleId=1 order by odp_routingcomponent .priority asc
It is wrong since not the table alias is used in the order by clause, but the real table name.
Mysql fails with exception that odp_rulecriteriajoin.priority is unknown table.
Changing the query to include "order by criteria0_.priority asc" returns the correct result.

incorrect hql query on one-to-one with property-ref

Project: Hibernate3
Type: Bug

Environment: hibernate 3.2.0.ga with firebird 1.5.3 and jaybird 1.5.5 driver on windows XP
Reporter: Sebastien Cesbron
Attachments: testhib.zip
I have a one-to-one relationship with property-ref between Master and Slave2.
I want to find all Master instances that have a null Slave2 instance associated.
To do so my query is
select master from Master master where master.slave2 is null
The sql generated is
select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_ where master0_.oid is null
which seems incorrect. It checks here Master instances with null id (config files are listed below).
If I do my query like this
select master from Master master where master.slave2.oid is null
the generated sql is ok :
select master0_.oid as oid0_, master0_.libelle as libelle0_ from Master master0_, Slave2 slave2x1_ where master0_.oid=slave2x1_.myMaster and (slave2x1_.oid is null)
I have attached a small eclipse project that reproduces the problem
This problem may-be related to the one I have submitted as issue HHH-1849

subselect fetching ignores max results
--------------------------------------
Key: HHH-2666
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2666
Project: Hibernate3
Issue Type: Improvement
Components: query-hql, query-sql
Affects Versions: 3.2.1
Environment: Hibernate 3.2.1
HSQLDB 8.0
Reporter: James Roper
Priority: Minor
When maxResults is set for a query, the hibernate subselect fetching strategy ignores it. For example, I have a class entry, that has a list of comments, which are configured to use the subselect fetching strategy. You can see that in the original query, only the top ? results are fetched:
select
top ? entry0_.id as id0_,
entry0_.title as title0_,
entry0_.entry as entry0_,
entry0_.time as time0_,
entry0_.category_id as category5_0_
from
Entry entry0_
order by
entry0_.time desc
But then when it does the sub select query to lazily load the comments, this is the query it runs:
select
comments0_.entry_id as entry5_1_,
comments0_.id as id1_,
comments0_.id as id1_0_,
comments0_.time as time1_0_,
comments0_.comment as comment1_0_,
comments0_.author as author1_0_
from
Comment comments0_
where
comments0_.entry_id in (
select
entry0_.id
from
Entry entry0_
)
order by
comments0_.time desc
So, it loads every single comment in the database, even though only the comments for the top ? entries are needed. Of course, if there was no order by clause on the first query, the sub select may not return the same results, so it should probably only do this when there is an order by clause in the first query, and it should make sure it includes the order by clause in the sub select.

Issue Type: Bug
Environment: Hibernate 3.2.2, Hibernate-annotations 3.2.1
Reporter: Suji Suresh
Hibernate has two ways of specifying a value for primary key:
1. Assign a value before handing it over to Hibernate
2. Have Hibernate generate the value before persisting
In my project I have objects of both of the above specified types. In other words I assign value for the primary key for some the objects (lets call these objects "assigned") and for others I have Hibernate generate the value before persisting (lets call these objects "generated"). Since Hibernate annotations does not support "unsaved-value", I do not have a way of specifying "unsaved-value" strategy. While my "generated" objects work perfectly with Hibernate's default "unsaved-value" strategy, I see wrong (but expected) behaviour when I try to persist an "assigned" object that is already present in the database in that, I get StaleStateException instead of DataIntegrityViolationException
