Removing dom4j?
by Jordan Gigov
So, the library has not seen a bugfix in over 10 years, and it lists the
wrong version for it's xml-apis dependency.
There are some notes in comments about eventually removing it, and I
thought I'd give it a try on the 5.2 branch.
I had to remove two shiv-libraries you had added to work around problems
you probably encountered prior to JDK6.
I've narrowed it down to 11 failing tests (5 distinct exceptions) when
using the default XML APIs provided with JDK8.
Is there any interest in this?

Favicon on CI
by Davide D'Alto
hi,
not critical, but I've upgraded the plugin for the Theme on Jenkins
and it is now possible to add a favicon from Jenkins settings page.
Just thought of mentioning it here in case we want to change the default one.
Cheers,

API incompatibilities between Hibernate ORM 5.3 and 6.0
by Gail Badner
I sent this last night with a huge report file, and it seems that it didn't
get out.
I'm re-sending without the report file...
I ran japi-compliance-checker to compare differences in APIs
between hibernate-core-5.3.0-SNAPSHOT.jar and hibernate-core-6.0.0-
SNAPSHOT.jar.
I ran it last week, so it may not include updates made since that time.
Differences in Envers shown in the report should be disregarded because it
only reflects that hibernate-envers was merged into hibernate-core. A
separate comparison between hibernate-envers-5.3.0-SNAPSHOT.jar and
hibernate-core-6.0.0-SNAPSHOT.jar needs to be done to see Envers changes.
Chris will provide details about Envers differences in a separate email.
The report is huge; it took me 3 to 4 hours to scan it. AFAICT, what I've
documented are the only non-Envers API changes that could affect
applications. They all involve removed classes/methods.
My intention here is just to get this information out, so we have some
solid examples to discuss.
Regards,
Gail
------------------------------------------------------------
----------------------------------------------------------------------
Custom types: I am not familiar with how this will work in 6.0. Steve,
please fill in details about any incompatibilities.
org.hibernate.Criteria and org.hibernate.criterion.DetachedCriteria:
In 5.0/5.1/5.2:
* user guides say, "This appendix covers the legacy Hibernate
org.hibernate.Criteria API, which should be considered deprecated. New
development should focus on the JPA javax.persistence.criteria.CriteriaQuery
API. Eventually, Hibernate-specific criteria features will be ported as
extensions to the JPA javax.persistence.criteria.CriteriaQuery. For details
on the JPA APIs, see Criteria."
In 5.2/5.3:
* Criteria and DetachedCriteria are not deprecated;
* all SharedSessionContract#createCriteria methods are deprecated;
* public static methods in DetachedCriteria are not deprecated;
In 6.0:
* Criteria and DetachedCriteria are removed along with other classes in
org.hibernate.criterion.
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications using legacy org.hibernate.Criteria will need to
be updated to use javax.persistence.criteria.CriteriaQuery;
2) If Hibernate's implementation of javax.persistence.criteria.CriteriaQuery
does not include the Hibernate-specific extensions that were available
using org.hibernate.Criteria, applications may not have a straightforward
way to change their applications to work.
org.hibernate.Query
In 5.1:
* SharedSessionContract#createQuery returns org.hibernate.Query
(org.hibernate.Session extends SharedSessionContract);
In 5.2/5.3:
* org.hibernate.Query was deprecated; org.hibernate.query.Query should be
used instead; org.hibernate.query.Query extends org.hibernate.Query;
* SharedSessionContract#createQuery moved to
org.hibernate.query.QueryProducer#createQuery,
returning org.hibernate.query.Query (which extends org.hibernate.Query);
(org.hibernate.Session extends QueryProducer);
In 6.0:
* org.hibernate.Query was removed.
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications that explicitly use org.hibernate.Query (including
javax.persistence.Query.unwrap( org.hibernate.Query.class )) will have to
be changed to use org.hibernate.query.Query.
org.hibernate.SQLQuery:
In 5.1:
* SharedSessionContract#createSQLQuery returns org.hibernate.SQLQuery
(org.hibernate.Session extends SharedSessionContract);
In 5.2/5.3:
* SQLQuery was deprecated; NativeQuery should be used instead; NativeQuery
extends SQLQuery;
* SharedSessionContract#createSQLQuery moved to
QueryProducer#createSQLQuery, returning NativeQuery (which extends
SQLQuery); Session extends QueryProducer;
* QueryProducer#createSQLQuery is deprecated; QueryProducer#createNativeQuery
should be used instead
In 6.0:
* SQLQuery and org.hibernate.query.QueryProducer#createSQLQuery are removed.
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications using Session#createSQLQuery will need to be
updated to use Session#createNativeQuery.
2) Existing applications that explicitly use org.hibernate.SQLQuery
(including javax.persistence.Query.unwrap( SQLQuery.class )) will have to
be changed to use NativeQuery.
org.hibernate.SynchronizeableQuery
In 5.2/5.3:
* org.hibernate.SynchronizeableQuery is not deprecated;
* SQLQuery, NativeQuery and ProcedureCall extend org.hibernate.
SynchronizeableQuery
In 6.0:
* org.hibernate.SynchronizeableQuery is moved to org.hibernate.query.
SynchronizeableQuery;
* NativeQuery and ProcedureCall extend
org.hibernate.query.SynchronizeableQuery;
(SQLQuery was removed as mentioned above)
Incompatibilities migrating from 5.3 -> 6.0:
1) In 6.0, existing applications that use org.hibernate.SynchronizeableQuery
(including javax.persistence.Query.unwrap(
org.hibernate.SynchronizeableQuery.class
)) will need to be updated to use org.hibernate.query.SynchronizeableQuery
org.hibernate.Session#createFilter
In 5.1:
* Session#createFilter returns org.hibernate.Query;
In 5.2/5.3:
* Session#createFilter returns org.hibernate.query.Query (which extends
org.hibernate.Query);
* org.hibernate.Session#createFilter is not deprecated;
In 6.0:
* org.hibernate.Session#createFilter is removed.
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications that call Session#createFilter will need to be
updated (to what???); does collection filter functionality exist in 6.0???
org.hibernate.Session.#getTypeHelper
In 5.1/5.2/5.3:
* org.hibernate.Session.#getTypeHelper returns org.hibernate.TypeHelper;
* Session#getTypeHelper is not deprecated;
In 6.0: org.hibernate.Session.#getTypeHelper is removed;
Incompatibilities migrating from 5.3 -> 6.0:
1) In 6.0, existing applications that call Session.#getTypeHelper will need
to be updated (to what???).
org.hibernate.metadata.ClassMetadata, org.hibernate.metadata.
CollectionMetadata
In 5.2/5.3:
* SessionFactory#getClassMetadata(Class), #getClassMetadata(String),
#getAllClassMetadata, #getCollectionMetadata, #getAllCollectionMetadata
were deprecated; descriptors from
javax.persistence.EntityManagerFactory#getMetamodel
should be used instead; org.hibernate.SessionFactory extends
javax.persistence.EntityManagerFactory;
In 6.0:
* ClassMetadata and CollectionMetadata removed.
Incompatibilities migrating from 5.3 -> 6.0:
1) In 6.0, existing applications that call
org.hibernate.SessionFactory#getClassMetadata(Class),
#getClassMetadata(String), #getAllClassMetadata, #getCollectionMetadata,
#getAllCollectionMetadata will need to be updated to use descripters from
javax.persistence.EntityManagerFactory#getMetamodel.
org.hibernate.stat.NaturalIdCacheStatistics
In 5.2/5.3:
* Statistics#getNaturalIdCacheStatistics returns NaturalIdCacheStatistics;
In 6.0:
* NaturalIdCacheStatistics is renamed to NaturalIdQueryStatistics;
* NaturalIdQueryStatistics excludes #getHitCount, #getMissCount,
#getPutCount, #getElementCountInMemory, #getElementCountOnDisk,
#getSizeInMemory, and #getEntries which were originally in
NaturalIdCacheStatistics; instead org.hibernate.stat.
SecondLevelCacheStatistics#getHitCount, #getMissCount, #getPutCount,
#getElementCountInMemory, #getElementCountOnDisk, #getSizeInMemory should
be used.
(SecondLevelCacheStatistics#getEntries was removed due to HHH-11356, so
there is no substitute for org.hibernate.stat.NaturalIdCacheStatistics#
getEntries;
* Statistics#getNaturalIdCacheStatistics is renamed to
#getNaturalIdStatistics.
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications that explicitly use NaturalIdCacheStatistics will
need to be updated to use NaturalIdCacheStatistics.
2) Existing applications that call Statistics#getNaturalIdCacheStatistics
will need to be updated to use Statistics#getNaturalIdCacheStatistics.
3) Existing applications that call org.hibernate.stat.
NaturalIdCacheStatistics#getHitCount, #getMissCount, #getPutCount,
#getElementCountInMemory, #getElementCountOnDisk, #getSizeInMemory, or
#getEntries will need to be updated to obtain the
SecondLevelCacheStatistics object for the particular natural ID using
Statistics#getSecondLevelCacheStatistics( naturalIdRegionName??? ) (How is
naturalIdRegionName determined???). The application will need to be changed
to used SecondLevelCacheStatistics#getHitCount, #getMissCount,
#getPutCount, #getElementCountInMemory, #getElementCountOnDisk, and
#getSizeInMemory instead.
4) Existing applications that call NaturalIdCacheStatistics#getEntries will
need to be updated to no longer call that method.
org.hibernate.stat.SecondLevelCacheStatistics
In 5.3:
* SecondLevelCacheStatistics#getEntries is not deprecated;
In 6.0:
* SecondLevelCacheStatistics#getEntries is removed due to HHH-11356.
* SecondLevelCacheStatistics no longer implements Serializable;
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications that call SecondLevelCacheStatistics#getEntries
will need to be updated to no longer call that method.
2) Existing applications that implement SecondLevelCacheStatistics (SPI)
will need to explicitly implement Serializable.
QueryStatistics#getCacheHitCount, #getCacheMissCount, and #getCachePutCount
In 5.3:
* QueryStatistics#getCacheHitCount, #getCacheMissCount, and
#getCachePutCount are not deprecated;
In 6.0:
* QueryStatistics#getCacheHitCount, #getCacheMissCount, and
#getCachePutCount were removed;
* ConcurrentQueryStatisticsImpl implements QueryStatistics and still
contains public methods, #getCacheHitCount, #getCacheMissCount, and
#getCachePutCount (why???).
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications that use
org.hibernate.stat.QueryStatistics#getCacheHitCount,
#getCacheMissCount, and #getCachePutCount will need to be changed (to use
SecondLevelCacheStatistics???).
org.hibernate.jpa.HibernateEntityManager
In 5.2/5.3:
* HibernateEntityManager is deprecated; Session (or SessionImplementor
(SPI)) should be used instead;
* Session extends HibernateEntityManager;
In 6.0:
* HibernateEntityManager is removed.
Incompatibilities migrating from 5.3 -> 6.0:
1) In 6.0, existing applications that explicitly use
org.hibernate.jpa.HibernateEntityManager
(including javax.persistence.EntityManager.unwrap(
HibernateEntityManager.class )) will have to be changed to use Session (or
SessionImplementor (SPI)).
org.hibernate.jpa.HibernateEntityManagerFactory
In 5.2/5.3:
* HibernateEntityManagerFactory is deprecated; SessionFactory (or
SessionFactoryImplementor (SPI)) should be used instead;
* SessionFactory extends HibernateEntityManagerFactory;
In 6.0:
* HibernateEntityManagerFactory is removed.
Incompatibilities migrating from 5.3 -> 6.0:
1) In 6.0, existing applications that explicitly use
org.hibernate.jpa.HibernateEntityManagerFactory
(including javax.persistence.EntityManagerFactory.unwrap(
HibernateEntityManagerFactory.class )) will have to be changed to use
Session (or SessionImplementor (SPI)).
org.hibernate.Hibernate#unproxy
In 5.2/5.3:
* Hibernate#unproxy was introduced by HHH-10831 in 5.2.10
In 6.0:
* the fix for HHH-10831 has not been incorporated into 6.0, so it is not
present. Will it be??
Incompatibilities migrating from 5.3 -> 6.0:
1) Existing applications that use Hibernate#unproxy will have to be be
changed to explicitly initialize and unproxy.

Empty IN list support
by Bregler, Jonathan
Hi,
HANA doesn't support empty IN lists, so executing an HQL query that gets transformed into a SQL query with an empty IN list results in a SQL parser error on the database side. I noticed that the Dialect class already defines a method called "supportsEmptyInList()" which according to the Javadoc returns "True if empty in lists are supported; false otherwise". However, this method doesn't seem to be used anywhere in the Hibernate code. Is there a reason for that?
Thanks,
Jonathan

Hibernate OGM integration with ORM 5.3
by Davide D'Alto
Hi,
I'm working on the integration with ORM 5.3 and I've created a branch
where I'm applying the changes.
You can see some initial discussions on the pull request I've sent as
preview: https://github.com/hibernate/hibernate-ogm/pull/961
I didn't find any specific issue with ORM 5.3 that could create a
problem for OGM so far.
Main problems are
1) check the JpaCompliance property and behave the same way as ORM
from a user point of view when possible
2) Positional parameters can now start from 1
3) The method that creates the factory doesn't thow exceptions anymoew
and in OGM we will have to do something similar when the OGM provider
is used
Anyway, it doesn't seem that these issues require changes in ORM.
I still have to update the integration tests with WildFly, so
something else might appears.
Cheers,
Davide

ORM 5.1 vs compatibility with Java 6
by Sanne Grinovero
Is Hibernate ORM 5.1 still meant to be compatible with Java 6?
The readme seems to promise that it should be, but it's not: I
happened to try compiling it and it failed, as some recent changes are
using JDK classes which have been introduced in 7.
Turns out it builds fine for Andrea an Chris, as they don't have the
JAVA6_HOME variable set: in this case the build will be lenient: log a
warning and move on.
I guess the same was done by all others on the team? CI is not
checking this either.
Wondering if you all feel like it's worth fixing branch 5.1, or if
it's a dead branch anyway.
Thanks,
Sanne
