Update all classes so that inner classes are always last. Also
ensure that utility classes are always final and have a private
constructor and make exceptions final whenever possible.

This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.

The main `build.gradle` file contains now only the common build
infrastructure; all module-specific build configurations have
been moved to their own build file.
Issue: SPR-15885
This commit ensure that null-safety is consistent between
getters and setters in order to be able to provide beans
with properties with a common type when type safety is
taken in account like with Kotlin.
It also add a few missing property level @Nullable
annotations.

This commits extends nullability declarations to the field level, formalizing the interaction between methods and their underlying fields and therefore avoiding any nullability mismatch.
Issue: SPR-15720
Beyond just formally declaring the current behavior, this revision actually enforces non-null behavior in selected signatures now, not tolerating null values anymore when not explicitly documented. It also changes some utility methods with historic null-in/null-out tolerance towards enforced non-null return values, making them a proper citizen in non-null assignments.
Some issues are left as to-do: in particular a thorough revision of spring-test, and a few tests with unclear failures (ignored as "TODO: NULLABLE") to be sorted out in a follow-up commit.
Issue: SPR-15540
This commit introduces 2 new @Nullable and @NonNullApi
annotations that leverage JSR 305 (dormant but available via
Findbugs jsr305 dependency and already used by libraries
like OkHttp) meta-annotations to specify explicitly
null-safety of Spring Framework parameters and return values.
In order to avoid adding too much annotations, the
default is set at package level with @NonNullApi and
@Nullable annotations are added when needed at parameter or
return value level. These annotations are intended to be used
on Spring Framework itself but also by other Spring projects.
@Nullable annotations have been introduced based on Javadoc
and search of patterns like "return null;". It is expected that
nullability of Spring Framework API will be polished with
complementary commits.
In practice, this will make the whole Spring Framework API
null-safe for Kotlin projects (when KT-10942 will be fixed)
since Kotlin will be able to leverage these annotations to
know if a parameter or a return value is nullable or not. But
this is also useful for Java developers as well since IntelliJ
IDEA, for example, also understands these annotations to
generate warnings when unsafe nullable usages are detected.

String with version 5 the name of Java Platform, Enterprise Edition
changed from J2EE to Java EE. However a lot of the documentation still
uses the term J2EE.
This commit includes the following changes:
* replace J2EE with Java EE where appropriate
This is not a blind search and replace. The following occurrences
remain unchanged:
* references to old J2EE releases, most notably 1.3 and 1.4.
* references to "Expert One-On-One J2EE Design and Development"
* references to "Core J2EE patterns"
* XML namespaces
* package names

This commit adds a "spring-context-indexer" module that can be added to
any project in order to generate an index of candidate components defined
in the project.
`CandidateComponentsIndexer` is a standard annotation processor that
looks for source files with target annotations (typically `@Component`)
and references them in a `META-INF/spring.components` generated file.
Each entry in the index is the fully qualified name of a candidate
component and the comma-separated list of stereotypes that apply to that
candidate. A typical example of a stereotype is `@Component`. If a
project has a `com.example.FooService` annotated with `@Component` the
following `META-INF/spring.components` file is generated at compile time:
```
com.example.FooService=org.springframework.stereotype.Component
```
A new `@Indexed` annotation can be added on any annotation to instructs
the scanner to include a source file that contains that annotation. For
instance, `@Component` is meta-annotated with `@Indexed` now and adding
`@Indexed` to more annotation types will transparently improve the index
with additional information. This also works for interaces or parent
classes: adding `@Indexed` on a `Repository` base interface means that
the indexed can be queried for its implementation by using the fully
qualified name of the `Repository` interface.
The indexer also adds any class or interface that has a type-level
annotation from the `javax` package. This includes obviously JPA
(`@Entity` and related) but also CDI (`@Named`, `@ManagedBean`) and
servlet annotations (i.e. `@WebFilter`). These are meant to handle
cases where a component needs to identify candidates and use classpath
scanning currently.
If a `package-info.java` file exists, the package is registered using
a "package-info" stereotype.
Such files can later be reused by the `ApplicationContext` to avoid
using component scan. A global `CandidateComponentsIndex` can be easily
loaded from the current classpath using `CandidateComponentsIndexLoader`.
The core framework uses such infrastructure in two areas: to retrieve
the candidate `@Component`s and to build a default `PersistenceUnitInfo`.
Rather than scanning the classpath and using ASM to identify candidates,
the index is used if present.
As long as the include filters refer to an annotation that is directly
annotated with `@Indexed` or an assignable type that is directly
annotated with `@Indexed`, the index can be used since a dedicated entry
wil be present for that type. If any other unsupported include filter is
specified, we fallback on classpath scanning.
In case the index is incomplete or cannot be used, The
`spring.index.ignore` system property can be set to `true` or,
alternatively, in a "spring.properties" at the root of the classpath.

Issue: SPR-11942
HibernateEntityManagerFactoryIntegrationTests in the spring-orm module
has been disabled for quite some time due to a dependency on the
AnnotationBeanConfigurerAspect from the spring-aspects module. Since
spring-aspects depends on spring-orm, a cyclical dependency would
result if this code were re-enabled "as is".
This commit removes the dependency on AnnotationBeanConfigurerAspect in
HibernateEntityManagerFactoryIntegrationTests by deleting all test code
and configuration related to @Configurable. In addition, this commit
also deletes all SessionFactory-specific test code in
HibernateEntityManagerFactoryIntegrationTests, allowing the test class
to focus on Hibernate as a JPA provider.
Issue: SPR-11922
This commit deletes all test annotations from the spring-orm module in
order to reduce unnecessary confusion between these "copies" and the
real, current versions of such classes in the spring-test module.
Furthermore, the legacy abstract JUnit 3.8 base classes and test cases
have been refactored accordingly.
Prior to this commit, the codebase was using a mix of log4j.xml
and log4j.properties for test-related logging configuration. This
can be an issue as log4j takes the xml variant first when looking
for a default bootstrap configuration.
In practice, some modules declaring the properties variant were
taking the xml variant configuration from another module.
The general structure of the configuration has also been
harmonized to provide a standard console output as well as an
easy way to enable trace logs for the current module.
- Fix Javadoc in HibernateTemplate so that it compiles in Eclipse.
- Suppress generics warnings in HibernateTemplateTests.
- Remove unnecessary deprecation warning suppression in constructor for
LocalSessionFactoryBuilder.
Note that this variant of HibernateTemplate is stripped down in terms of Session management options and just provides a current-session style with a fallback to a temporary session-per-operation. Furthermore, in the latter fallback mode, only read operations are supported, just like with a JPA EntityManager.

Issue: SPR-10874
Since Hibernate 3.6 and 4.x differ in exception handling now, this change makes HibernateJpaDialect independent from orm.hibernate3 now and avoids introducing a conditional dependency on orm.hibernate4.
Issue: SPR-10815
Fix PersistenceUnitReader to correctly read <exclude-unlisted-classes>
in both JPA 1.0 and 2.0 persistence.xml files.
Prior to this commit PersistenceUnitReader would set the value of
excludeUnlistedClasses to true when a <exclude-unlisted-classes> element
was present, regardless of its value.
The following rules are now used when parsing:
- If the <exclude-unlisted-classes> element is missing the appropriate
default value is set (based on the JPA version).
- If an empty <exclude-unlisted-classes/> element is found the
excludeUnlistedClasses property is set to true.
- Otherwise the value of the <exclude-unlisted-classes> element is used
to set the excludeUnlistedClasses property.
Issue: SPR-10767
Fix SharedEntityManagerCreator.createSharedEntityManager to correctly
forward an empty array in case that EntityManagerFactoryInfo returns
null from getEntityManagerInterface().
Previously the var-args invocation had turned null into an array with
a null value which caused a NullPointerException in the call to
Proxy.newProxyInstance() further down the call stack.
Issue: SPR-10678
HibernateJpaDialect's HibernateConnectionHandle does not call close() for Hibernate 4.x anymore, since on 4.2, the exposed Connection handle isn't a "borrowed connection" wrapper but rather the actual underlying Connection - with a close() call immediately returning the Connection to the pool and making the local handle invalid for further use within the transaction.
Also using JPA 2.0's EntityManager unwrap method now for retrieving the underlying Hibernate Session.
Issue: SPR-10395
In the course of this effort, our joinTransaction() support has been overhauled to work for shared EntityManagers as well, since an unsynchronized shared EntityManager will nevertheless be scoped for the current transaction but not automatically join it (as per the JPA 2.1 spec). In the JTA case, we'll simply create an unsynchronized target EntityManager and will upgrade it to a synchronized one (later in the same transaction, if necessary) through an implicit joinTransaction() call. In the JpaTransactionManager case, we'll unbind the primary target EntityManager and will expose an unsynchronized EntityManager instead, upgrading it the same way as with JTA, with the primary EntityManager in that case just serving as a vehicle for transaction begin/commit/rollback calls.
For extended EntityManagers, we've just added further combinations to the existing variants: application-managed EntityManagers which may nevertheless auto-join transactions (EntityManagerFactory.createEntityManager with SynchronizationType.SYNCHRONIZED), and container-managed EntityManagers which might opt for not auto-joining transactions (@PersistenceContext with synchronizationType=UNSYNCHRONIZED).

The files deleted in this commit existed in identical form in two places
within a given module; typically in src/test/java and
src/test/resources. The version within src/test/resources has been
favored in all cases.
This change was prompted by associated Eclipse warnings, which have now
been quelled.
Issue: SPR-9431
Prior to this commit many test utility classes and sample beans were
duplicated across projects. This was previously necessary due to the
fact that dependent test sources were not shared during a gradle
build. Since the introduction of the 'test-source-set-dependencies'
gradle plugin this is no longer the case.
This commit attempts to remove as much duplicate code as possible,
co-locating test utilities and beans in the most suitable project.
For example, test beans are now located in the 'spring-beans'
project.
Some of the duplicated code had started to drift apart when
modifications made in one project where not ported to others. All
changes have now been consolidated and when necessary existing tests
have been refactored to account for the differences.
