JUnit 5.13 introduced support for Discovery Issues which typically
indicate configuration errors in tests that may result in unexpected
behavior.
Furthermore, discovery issues that are currently reported at INFO level
may later be reported at WARNING or ERROR level -- for example, in
JUnit 6.
In order to ensure that our test suite does not suffer from such
potential errors, this commit sets the
junit.platform.discovery.issue.severity.critical JVM system property to
INFO (instead of leaving it with the default ERROR configuration).
Doing so aligns with our build configuration which fails the build for
selected warnings in Java source code and Javadoc.
If we later determine that INFO causes unnecessary issues for us, we
can switch to WARNING.
This commit also removes two "intentionally invalid" test cases from
AutowiredConfigurationErrorsIntegrationTests, since those test cases
are now reported as invalid as of JUnit 5.13.

Kotlin 2.2 is the new baseline for Spring Framework 7.0.
-Xannotation-default-target=param-property is specified to avoid
warnings when compiling tests or documentation snippets. It is
expected to become the default behavior in an upcoming version
of Kotlin, see https://youtrack.jetbrains.com/issue/KT-73255 for
more details.

Historically, we have used `<introduction year>-<modification year>` as
the pattern for copyright headers.
For example: `Copyright 2002-2025 the original author or authors.`
However, we have been encouraged to use `present` as the modification
year.
In light of that, this commit updates the following to enforce the new
pattern.
- The patterns in our SpringHeaderCheck Checkstyle rules
- The `Copyright 2002-${year}` template in org.eclipse.jdt.ui.prefs
- The update_copyright_headers.sh script
See gh-35070

While we choose our GitHub action to use Bellsoft Liberica, we should
relax that vendor requirement and ensure that contributors can build the
project with any Java 24 distribution.

In commit 49ef150c5d, I stated that the common javadoc task used by all
spring-* modules would be addressed in a separate commit. However,
after further investigation I determined that the spring-test Javadoc
JAR was published successfully, including links to JUnit 5 Javadoc
(which was not previously the case).
https://repo1.maven.org/maven2/org/springframework/spring-test/7.0.0-M4/spring-test-7.0.0-M4-javadoc.jar
This commit therefore only adds a note in JavaConventions to remind us
that the aggregated Javadoc toolchain configuration needs to stay in
sync with the configuration in JavaConventions.

This commit revises the implementation of TestConventions so that
existing JUnit Platform options from a pre-configured `test` task are
copied instead of overridden.
Closes gh-34827
This commit revisit the build configuration to enforce the following:
* A single Java toolchain is used consistently with a recent Java
version (here, Java 23) and language level
* the main source is compiled with the Java 17 "-release" target
* Multi-Release classes are compiled with their respective "-release"
target. For now, only "spring-core" ships Java 21 variants.
Closes gh-34507
The spring-jcl module no longer exists on main, but it still exists on
the 6.2.x branch and previous branches and can cause build failures when
switching between branches.
This commit adds a new custom build Plugin, the `ArchitecturePlugin`.
This plugin is using ArchUnit to enforce several rules in the main
sources of the project:
* All "package-info" should be `@NullMarked`
* Classes should not import forbidden types (like "reactor.core.support.Assert"
* Java Classes should not import "org.jetbrains.annotations.*" annotations
* Classes should not call "toLowerCase"/"toUpperCase" without a Locale
* There should not be any package tangle
Duplicate rules were removed from checkstyle as a result.
Note, these checks only consider the "main" source sets, so test
fixtures and tests are not considered. Repackaged sources like JavaPoet,
CGLib and ASM are also excluded from the analysis.
Closes gh-34276
In order to be able to fix gh-34140 which requires using at least a
Java 22 compiler, this commit intends to change the configuration of
the Gradle toolchain to use Java 23, while setting the Java release to
Java 17 (or other versions when using MRJARs) when relevant in order to
keep the current Java 17 baseline.
See gh-34220
Spring Framework 7.0 will use a Kotlin 2 baseline, using the latest 2.x
release at the time of the release.
This commit upgrades Kotlin to 2.1.0, and Kotlin Serialization and
Coroutines accordingly.
Closes gh-33629
This commit adds a DSL Gradle extension for optionally enabling Java
preview features in a specific project module. The "--enable-preview"
JVM flag will be configured automatically for compile and test tasks
where this is applied:
```
springFramework {
enableJavaPreviewFeatures = true
}
```
See gh-33616
Prior to this commit, the Gradle build output the following warning
multiple times.
OpenJDK 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended
Since we don't need CDS enabled for our tests, I've added `-Xshare:off`
as a JVM argument for our tests to disable CDS.
