This commit updates the whole Spring Framework codebase to use JSpecify
annotations instead of Spring null-safety annotations with JSR 305
semantics.
JSpecify provides signficant enhancements such as properly defined
specifications, a canonical dependency with no split-package issue,
better tooling, better Kotlin integration and the capability to specify
generic type, array and varargs element null-safety. Generic type
null-safety is not defined by this commit yet and will be specified
later.
A key difference is that Spring null-safety annotations, following
JSR 305 semantics, apply to fields, parameters and return values,
while JSpecify annotations apply to type usages. That's why this
commit moves nullability annotations closer to the type for fields
and return values.

This commit makes sure that the programmatic exception that is thrown
by the cache abstraction uses the same message structure as a default
message produced by NoUniqueBeanDefinitionException.
Closes gh-33305
This commit replaces the IllegalStateException thrown in
CacheAspectSupport when a CacheManager cannot be determined. These were
added to provide a dedicated error message, but it is possible to do
so without hiding the more adequate exception type.
Closes gh-22442
Includes rollbackOn annotation attribute on @EnableTransactionManagement and addDefaultRollbackRule method on AnnotationTransactionAttributeSource, as well as publicMethodsOnly as instance-level flag (also on AnnotationCacheOperationSource).

This commit deprecates the various nullSafeHashCode methods taking array
types as they are superseded by Arrays.hashCode now. This means that
the now only remaining nullSafeHashCode method does not trigger a
warning only if the target type is not an array. At the same time, there
are multiple use of this method on several elements, handling the
accumulation of hash codes.
For that reason, this commit also introduces a nullSafeHash that takes
an array of elements. The only difference between Objects.hash is that
this method handles arrays.
The codebase has been reviewed to use any of those two methods when it
is possible.
Closes gh-29051
This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
This commit picks up where the two previous commits left off.
Specifically, this commit:
- Removes the "severity=warning" configuration to ensure that violations
actually fail the build.
- Fixes regular expressions for suppressions by matching forward
slashes using `[\\/]` instead of `\/`.
- Moves the configuration for newly introduced checks to locations in
checkstyle.xml that align with the existing organization of that file.
- Renames the IDs for RegexpSinglelineJava checks from
javaDocPackageNonNullApiAnnotation/javaDocPackageNonNullFieldsAnnotation
to packageLevelNonNullApiAnnotation/packageLevelNonNullFieldsAnnotation,
respectively, since these checks are not related to Javadoc.
- Simplifies the null-safety annotation checks to match against
imported annotation types, which enforces consistency across
package-info.java files for the annotation declarations.
- Simplifies the RegEx for JavadocPackage suppressions to only exclude
packages not under src/main/java (vs src/main) and those in the
framework-docs module.
- Consistently suppresses all checks for the `asm`, `cglib`, `objenesis`,
and `javapoet` packages in spring-core.
- Adds explicit suppressions for null-safety annotations for the `lang`
package in spring-core.
- Adds explicit suppressions for null-safety annotations for the
`org.aopalliance` package in spring-aop.
- Revises the RegEx for null-safety annotation suppressions to only
exclude package-info.java files not under src/main/java and
additionally to exclude package-info.java files in the framework-docs
module as well as those in the spring-context-indexer,
spring-instrument, and spring-jcl modules.
- Adds all missing package-info.java files.
- Adds null-safety annotations to package-info.java files where
appropriate.
