In our tests, the JNI code in Netty tcNative can cause some of its
classes to be loaded using a ModifiedClassPathClassLoader. When the
wrong class loader is used, SSL-related tests fail, for example due
to the same Netty tcNative classes being loaded by two different
ClassLoders and no longer being the same. This appears to be
dependent upon the order in which tests are executed and results in
intermittent test failures.
It looks like this should be addressed in Netty tcNative 2.0.40 which
preloads all of its classes. In the meantime, this commit updates
ModifiedClassPathClassLodaer to ignore Netty tcNative classes so that
they're only ever loaded by the system class loader.
Closes gh-26749
Previously, Spring Boot's modules published Gradle Module Metadata
(GMM) the declared a platform dependency on spring-boot-dependencies.
This provided versions for each module's own dependencies but also had
they unwanted side-effect of pulling in spring-boot-dependencies
constraints which would influence the version of other dependencies
declared in the same configuration. This was undesirable as users
should be able to opt in to this level of dependency management, either
by using the dependency management plugin or by using Gradle's built-in
support via a platform dependency on spring-boot-dependencies.
This commit reworks how Spring Boot's build uses
spring-boot-dependencies and spring-boot-parent to provide its own
dependency management. Configurations that aren't seen by consumers are
configured to extend a dependencyManagement configuration that has an
enforced platform dependency on spring-boot-parent. This enforces
spring-boot-parent's version constraints on Spring Boot's build without
making them visible to consumers. To ensure that the versions that
Spring Boot has been built against are visible to consumers, the
Maven publication that produces pom files and GMM for the published
modules is configured to use the resolved versions from the module's
runtime classpath.
