ConnectionWrapper is not visible from class loader
---------------------------------------------------
Key: HHH-3529
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3529
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1, 3.2.6
Environment: SpringFramework 2.5.5, Hibernate 3.2.6 / 3.3.1, Tomcat 5.5, CommonJ Timer ( http://www.myfoo.de/commonj/ )
Reporter: Vladimir Kralik
Attachments: hibernate-3.2.6_p2.patch
Hibernate/Spring libraries are in app.war/WEB-INF/lib.
Timer is configured as resources in Tomcat and his libraries are in $CATALINA_HOME/common/lib/.
Function call from GUI works, but the same function called by timers gives this exception :
org.springframework.transaction.CannotCreateTransactionException: Could not openHibernate Session for transaction; nested exception is java.lang.IllegalArgumentException:
interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader
at org.springframework.orm.hibernate3.HibernateTransactionManager.doBegin(HibernateTransactionManager.java:599)
....
Caused by: java.lang.IllegalArgumentException: interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader

at org.springframework.orm.hibernate3.HibernateTransactionManager.doBegin(HibernateTransactionManager.java:510)
It's the same bug as was in HHH-2215, but this is not resolved.
I think, that the problem is extracting classloader from currentThread(). This is always not null, so the next test in method getProxyClassLoader() is always false.
I my case, timer thread lives in top class loader, but hibernate libraries are inside application class loader.
Attached patch removes classloader extracting from currentThread(). It works for my case.

@JoinColumn overrides scale and percision in ManyToOne map..
------------------------------------------------------------
Key: ANN-748
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-748
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.4.0.CR1
Environment: Postgresql but not Hypersonic (haven't tried other DBs, but suspect any real non-java db will replicate)
Reporter: Andrew C. Oliver

Since you asked nicely...
This is a patch against your test cases.
Sorry for the not patch style patch. It is against the latest download of Annotations (3.4.0.CR1). I'm on a hotel network that seems to really make SVN angry.
There are 4 files:
1. Bunny has many
2. PointyTooth (teeth)
3. IdTest.java, only "testBlownPrecision" is new and "getMappings" includes the rabid bunny and teeth
4. UUIDGenerator - I wouldn't have included it but I couldn't find a decent way to autogenerate 128-bit keys. (The linked wikipedia article is amusing).
You'll probably want to unzip these into the annotations root directory, then do the svn diff. Following this you may want to pretty print.
As the test notes, it will FAIL with the @JoinColumn mapping and succeed if it is commented out. The failure notes a precision error. Obviously batching must be disabled to read it. If you look at the generated table it will have like NUMBER[19]. With JoinColumn commented out it is the expected NUMBER[128]. Thanks to PaaKow Acquah for finding this.
If you want more details, I'll be a TacoMac having another Aventinus...

Affects Versions: 3.2.0.GA
Reporter: Ashish Zokarkar
Hello,
I am using hbm2java ant task for creation of java classes from hbm.xml files. I am using
hibernate-tools-3.2.0.beta9a.jar
hibernate3.jar
jcl-over-slf4j-1.5.8.jar
slf4j-api-1.5.8.jar
slf4j-jcl-1.5.8.jar
When I run this task, I get StackoverflowError. But when i try same ant script with
hibernate-3.1.3.jar
hibernatetools-3.1.0-b4.jar
it executed properly. But with hibernate-tools-3.2.0.beta9a & slf4j related jars I got StackOverflowExcpetion.
Ant script is as below:
<project default="hbm2java">
<property name="build.dir" location="." />
<property name="lib.dir" location="lib" />

</target>
</project>
Please suggest me how to run this command with new build. Is it a bug in this build?

[Hibernate-JIRA] Created: (HHH-3589) Sql generated for criteria intermittently causes "invalid identifier" error by assigning incorrect table alias to query elements
by Todd Currie (JIRA)
Sql generated for criteria intermittently causes "invalid identifier" error by assigning incorrect table alias to query elements
--------------------------------------------------------------------------------------------------------------------------------
Key: HHH-3589
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3589
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1
Environment: Hibernate Core 3.3.1.GA
Oracle 10.02.03
JRE Q1.5.0_16-b02
Reporter: Todd Currie
Application is encountering intermittent ORA-00904 "invalid identifier" errors in production and test build environment. Error occurs approximately 1:460 executions in the test build environment. In each occurence it happens with a different test, but when it occurs every criteria query generated for that test class fails. In production typically causes application to crash because of the unexpected exception thrown.
The issue appears to be caused during construction of the CriteriaJoinWalker. The CriteriaLoader creates a CriteriaQueryTranslator that is responsible for the where condition and order by for non-projection queries (or additionally the select and group by for projection queries). The translator constructor is passed the CriteriaQueryTranslator.ROOT_SQL_ALIAS, "this_", which it uses for its rootSQLAlias. But when the CriteriaLoader next creates the CriteriaJoinWalker instance that is responsible for the rest of the query elements, it does not use the constructor that takes the root alias. The CriteriaJoinWalker then calls super(persister, factory, enabledFilters, alias); with a null passed in the alias parameter. The constructor in the parent class, AbstractEntityJoinWalker, calls generateRootAlias when the alias parameter is null. The method generateRootAlias is implemented both in the parent class JoinWalker and the child class CriteriaJoinWalker. To implement this form of polymorphism, java uses dynamic method binding to determine which method to call for the instance at run time. It appears that most of the time it calls the CriteriaJoinWalker implementation of generateRootAlias function which is hard coded to return CriteriaQueryTranslator.ROOT_SQL_ALIAS, "this_". The queries then generated by the CriteriaJoinWalker then execute correctly. But intermittently it calls the JoinWalker implementation which uses the passed in persistor's entityName to generate the table alias. This table alias that is then used for the rest of the query is different then the alias used by the CriteriaQueryTranslator and the resulting sql generates the invalid identifier error seen upon execution.
This can be fixed in a number of ways.
1) pass the CriteriaQueryTranslator.ROOT_SQL_ALIAS into the constructor for the CriteriaJoinWalker.
2) make the generateRootAlias abstract in the JoinWalker (less reliable).
3) use an AbstractFactory pattern to construct the objects (more work).
I have implemented #1 in our environment and am working on generating a clean test case to submit here. But for those who are interested here is the patch:

It seems It happens when hibernate session was cleared so proxy.lazyInitializer.session is set to null but this object can be used later as refernce in other entity.
Just for information such use case works OK with hibernate without Envers as far as we not try call getters of proxy with null session.

ToOneDelegateSessionImplementor breaks Hibernate.getClass(auditedEntity.proxyOfnotAuditedEntity)
------------------------------------------------------------------------------------------------
Key: HHH-4437
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4437
Project: Hibernate Core
Issue Type: Bug
Components: envers
Affects Versions: 3.3.x
Reporter: Eugene Goroschenya
Priority: Blocker
Probably there is mistake in changes applied for HHH-4010 that leads to incorrect working of Hibernate.getClass(proxy) method.
See ToOneDelegateSessionImplementor#doImmediateLoad(String entityName)
...
Session session = versionsReader.getSession();
return session.get(entityClass, (Serializable) entityId);
...
It can return proxy but Hibernate SessionImplementor interface says
/**
* Load an instance immediately. This method is only called when lazily initializing a proxy.
* Do not return the proxy.
*/
public Object immediateLoad(String entityName, Serializable id) throws HibernateException;
Probably solution is to use delegate.doImmediateLoad(entityClass, (Serializable) entityId) instead of session.get(entityClass, (Serializable) entityId)
