Change log level for one of the log messages in NamedQuery from INFO to WARN. This was done to provide more forceful information to the developer that sorting applied with named queries will be ignored.
The fixed versions caused issues when used with newer versions of Spring. Removing the version number will cause the one used at runtime to be pulled in.
Override isPersistenceUnitOverrideAllowed() newly introduced in Spring 3.1.1 to indicate we can deal with persistence units of the same name. For Spring 3.0.x versions the implementation was not broken.
Removed @Required annotation from the setter for EntityManager property. The annotation triggered a dependency check that was not aware of the EntityManager being injected by a PersistenceAnnotationBeanPostProcessor. As we already have a validation callback using @PostConstruct we can simply rely on the not-null check for the EntityManager being implemented there.
JpaQueryCreator hands Comparable into ParameterExpressionProvider to create ParameterExpression instances for Comparables. The ParameterExpressionProvider in turn now inspects the actual Parameter type and hand this one into the builder in case it's assignable (read: more concrete) to the given type requested.
Mention PersistenceExceptionTranslator being activated when using the JPA namespace. Documented custom namespace attributes special to the JPA namespace.
Added handling of count methods for queries using group by. In case the count query returns multiple results we use the number of results instead of failing. If the result contains one result we use this one.
We now don't catch an IllegalArgumentException being thrown in case a domain class is not found in the metamodel. If it occurs there's nothing we can do about it as we can't come up with an EntityInformation instance then and the persistence provider couldn't handle it anyway.
Fixed potential concurrency problem for PartTree based query creation. JpaQueryCreator is stateful as we create a list of ParameterExpressions and iterate over them. So we have to re-instantiate the JpaQueryCreator to not create an exception on the second attempt. We now eagerly create CriteriaQuery and it's ParameterExpressions in QueryPreparer's constructor. Lazily doing so could let to exceptions accessing the ParameterExpressions in race conditions.
Added Sonargraph architecture description. Removed cyclic package dependency. Introduced JpaEntityInformationSupport to contain common getEntityName() method and serving as factory for JpaEntityInformation instances.
Upgraded to Querydsl 2.2.0. Added configuration to generate query classes for AbstractPersistable and AbstractAuditable. Package those query classes into the source JAR and compile it into the binary as well. Upgraded Mysema APT plugin to 1.0.2.
