Documentation for native executables, CDS, and checkpoint/restore are
now under a common heading in the reference documentation, along with
sections on building container images. A few sections containing
prescriptive workflows have been moved from reference to how-to guides.
This consolidates and improves the consistency of recommendations on
how to package and run applications.
Closes gh-40977
The test CNB builder and buildpack used in integration tests have moved
from a projects.registry.vmware.com registry to ghcr.io/spring-io. This
commit modifies tests to use the new location.
Closes gh-40800
When the `buildWorkspace` location in the
`spring-boot:build-image` Maven goal or `bootBuildImage` Gradle
task is configured to use a local bind source, the location
is passed to the CNB lifecycle without further processing by
Spring Boot. The lifecycle is in control of creating any files
in the specified location. Spring Boot tries to remove the
directories at the specified location after an image is
successfully created, but should not fail the image build
if the lifecycle has created files or directories with
permissions that keep them from being deleted successfully.
Fixes gh-40760
Update `Path` creation for nested locations to allow both UNC and classic
file references to be used. This commit attempts to align our URL
handling with that of standard file URLs. The `NestedLocation` class
no longer attempts to remove leading all `\` characters and instead
only removes the first `\` when the second char is `:`. This duplicates
the logic found in Java's own internal `WindowsUriSupport` class which
is used when calling `Path.of(url)` with a `file:` URL.
Fixes gh-40549
In order to support Java 22, we must use spring-core 6.1.x.
spring-core 6.1.x is a multi-release jar so, in order to support Java
22, a version of Gradle that supports multi-release jars must be
used.
This commit adds a new variant to spring-boot-gradle-plugin for
modern versions of Gradle. When Gradle's plugin API version is 8.7 or
later, we use spring-core 6.1.x. spring-core 6.0.x is used at all
other times.
Closes gh-40074
Fix regression in `JarUrlConnection` where a NullPointerException could
be thrown internally causing performance issues.
When the SecurityManager is present, the following stack trace is
thrown:

Update buildpack support to allow gzip compressed image layers to be
used when returned by the Docker engine. This update is restores
buildpack support when using Docker Desktop with the "Use containerd
for pulling and storing images" option enabled.
This commit introduces a new `ExportedImageTar` class to deal with the
intricacies of determining the mimetype of a layer. The class deals with
the parsing of `index.json' and related manifest blobs in order to
obtain layer information. The legacy `manifest.json` format is also
supported should `index.json` be missing.
Tests have been added to ensure that export archives from Docker Engine,
Docker Desktop (with and without containerd), and Podman can be used.
Fixes gh-40100
