Update `LaunchedURLClassLoader` so that packages defined from exploded
archive folders have manifest attributes applied to them. Prior to this
calling `package.getImplementationTitle()` would only return the a
manifiest attribute when running non-exploded.
The root cause of this issue is the way that `URLClassLoader` handles
the different URL types. For URLs that reference a jar the manifest is
available. For URLs that reference a folder it isn't. When running
exploded we use a URL that references to the `BOOT-INF/classes` folder
directly. To fix the issue we now attempt to detect when `definePackage`
is being called directly, and replace `null` entries with actual
manifest values.

Update `SpringBootServletInitializer` to use the `ServletContext` that
was provided to the initial `onStartup` call rather than the
one from the `ServletContextEvent`. This allows the `getClassLoader()`
call to complete without throwing an `UnsupportedOperationException`.

This commit improves the error messages returned by the Spring Boot
build plugins when a 5xx status code is returned from the Docker
API while attempting to build an image. If the error response has
contents containing a JSON structure with a "message" key, the value
associated with that key will be included in the exception message
and in the build plugin output error.
Fixes gh-21515
Update `SpringConfigurationPropertySource` so that wrapped random
property sources can be used. It's assumed that wrapped random
sources will use the name of the source as the prefix.
Closes gh-21595
Previously, if the Spring Boot build plugins got a connection error
when attempting to communicate with a Docker daemon (for example,
when the daemon isn't running), the error message made it appear that
the daemon returned an HTTP error code. This commit makes a connection
error distinct from an HTTP error response code to make it easier for
the user to diagnose the root cause of the problem.
Fixes gh-21554
Previously, an AvailabilityChangeEvent was published when the servlet
and reactive web server application contexts were closed, irrespective
of whether or not the context was active. This caused problems when
the context was not active due to a refresh failure as the event
publication could then trigger bean creation and post-processing that
relied upon beans that had been destroyed when cleaning up after the
refresh failure. The most commonly seen symptom was a missing
importRegistry bean that is required by ImportAwareBeanPostProcessor.
This commit updates the two web server application contexts to only
publish the availability change event if the context is active.
Fixes gh-21588
Previously, the productionRuntimeClasspath configuration was created
without any attributes. This caused problems with multi-project
dependency resolution as there was insufficient information for Gradle
to determine which variant of a dependency should be used by the
productionRuntimeClasspath configuration.
This commit updates the configuration to have three attributes, each
configured with the same values as those of Gradle's own
runtimeClasspathConfiguration.
Fixes gh-21549
This commit mentions the `management.health.probes.enabled`
configuration property in the Kubernetes Probes section of the Actuator
chapter.
Enabling this property is required if we need to expose Kubernetes
Probes in a non-Kubernetes environment.
Fixes gh-21505
Prior to this commit, Spring Boot would auto-configure Spring MVC and
would keep the default `UrlPathHelper` configuration.
Since Spring Boot is in charge of configuring the `DispatcherServlet`
and its mapping, it is in a position to optimally configure the
`UrlPathHelper` depending on the chosen mapping.
This commit sets the `alwaysUseFullPath` property of `UrlPathHelper` if
the Servlet mapping is `"/"`. This is more efficient since this
configuration requires less processing of the request path.
