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.

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.

Refine the fix for gh-38611 so that `ClosedByInterruptException` no
longer retries in a loop.
Our previous fix was flawed due to the fact that another interrupt
could occur after we clear the first and whilst we are reading data.
If this happens 10 times in a row, we raise an exception and end up
causing NoClassDefFoundError errors.
Our new approach retains the use of `FileChannel` and a direct buffer
up to the point that a `ClosedByInterruptException` is raised or the
thread is detected as interrupted. At that point, we temporarily
switch to using a `RandomAccessFile` to access the data. This will
block the thread until the data has been read.
Fixes gh-40096
Rename the internal `FileChannelDataBlock` to `FileDataBlock` since we
want to fallback to a `RandomAccessFile` when a thread is interrupted.
See gh-40096
Update `anchor-rewrite.properties` to fix a few errors and remove
elements that no longer exist. This commit also fixes a few anchors
in some `.adoc` files.
See gh-40062
ZipInputStream can't cope with some non-deflated entries, see
https://bugs.openjdk.org/browse/JDK-8143613.
JarFile works better, but it doesn't support creation time / access
time.

It now extracts the contents of the JAR in a folder named after the JAR
without the extension. It now also checks if the folder is empty.
There's a new --force option to skip those checks.
The "runner.jar" is now named like the uber JAR from which the
extraction has been started.
See gh-38276
Adds a new jarmode called 'tools'. This provides two commands,
'extract' and 'list-layers'. list-layers is the same as list from
the layertools.
extract is able to extract the JAR in four different modes:
- CDS compatible extraction with libraries in a lib folder and a runner
.jar
- CDS compatible as above, but with layers
- Launcher based
- Launcher based with layers. This is essentially the same as extract
from the layertools
The commands in layertools have been deprecated in favor of the commands
in 'tools'.
This also changes the behavior of layers.enabled from the Gradle and
Maven plugin: before this commit, layers.enabled prevents the inclusion
of the layer index file as well as the layertools JAR.
After this commit, layers.enabled only prevents the inclusion of the
layer index file.
layer.includeLayerTools have been deprecated in favor of includeTools,
and the layertools JAR has been renamed to tools.

URL can contains empty spaced encoded as %20, so it should be decoded
before passing it to NestedLocation. NestedLocation expects file system
path which should not contain URL encoded values.

Update the regular expression used to parse Docker images references to
prevent catastrophic backtracking when images names are long and the
tag contains an illegal character.
See gh-39617
The logic to extract layers from a downloaded Docker image assumed that
the layer entries in the image tar archive always had the file extension
`.tar`. This was the case with Docker and other compatible daemons until
Docker 25.0. With this commit, the extension is no longer assumed, but
any entries listed in `manifest.json` will be recognized.
Fixes gh-39323
Update `NestedJarFile` so that the `getManifest()` method returns the
manifest from the parent jar file for nested jars based on directory
entries.
This restores the previous behavior supported by Spring Boot 3.1 and
allows class methods such as `getPackage().getImplementationVersion()`
to return non `null` results.
Fixes gh-38996
Update `ZipContent` so that `META-INF` entries are no longer duplicated
in nested jars created from directory entries. This aligns with the
behavior of the classic loader and prevents the same META-INF file from
being discovered twice.
Fixes gh-38862
Update `JarFileArchive` so that unpacked jars use `file:` URLs rather
than `jar:file:`. This aligns with the behavior of Spring Boot 3.1 and
allows calls to `class.getSigners()` to work again.
Fixes gh-38833

In gh-38154, we started handling ClosedByInterruptException. The
FileChannel was repaired by recreating it and then the exception was
rethrown. This allowed other threads to use the channel that had been
read by an interrupted thread while allowing that interruption to
continue.
This approach has proven to be insufficient as there are scenarios
where the read needs to succeed on the interrupted thread. This
commit updates the handling of ClosedByInterruptException so that
this is the case. The FileChannel is recreated as before but the
thread's interrupted flag is now cleared before retrying the read.
The flag is then reinstated so that any subsequent actions that
should fail due to the interruption will do so.
We could clear and reinstate the interrupted flag before the first
read, rather than catching ClosedByInterruptException. This approach
was rejected as it will have an impact on the performance of the
happy path where the thread hasn't been interrupted.
Fixes gh-38611
Relax the constraint that a `NestedLocation` must have a nested entry
name specified so that URLs can be split and rebuilt.
Prior to this commit, given a URL of the following form:
jar:nested:/myjar.jar!/nested.jar!/my/file
It was possible to create a FileSystem from
"jar:nested:/myjar.jar!/nested.jar" and from that create a path to
"my/file".
However, it wasn't possible to create a FileSystem from
"jar:nested:/myjar.jar", then create another file system from the path
"nested.jar" and then finally create a path to "/nested.jar".
This was because `nested:/myjar.jar` was not considered a value URL
because it didn't include a nested entry name.
Projects such as `JobRunr` were relying on the ability to compose file
systems, so it makes sense to remove our somewhat artificial
restriction.
Fixes gh-38592
Update `NestedByteChannel.read` so that it loops until all
remaining data has been read into the buffer. Prior to this
commit, it was possible for to read only some bytes into the
buffer. Although it looks like this should be OK according to
the API documentation, the `ZipFileSystem` relies on all
remaining bytes being returned.
Fixes gh-38595
Update `ZipContent` so that `eocd.totalNumberOfCentralDirectoryEntries`
is converted from a short to an unsigned int to prevent a negative
number from being used.
This commit also updates the code to consistently use `X.toUnsigned...`
helper methods rather than using bitwise operators.
Fixed gh-38572
Update jar `Handler` code so that the `parseUrl` method can accept an
empty `spec`. Prior to this commit, a `classLoader.getResource("")`
call would result in a `null` result. This breaks a number of things
including `ClassPathResource` and `PathMatchingResourcePatternResolver`.
Fixes gh-38524
Update `JarUrlConnection` and `NestedUrlConnection` so that calls
to `getLastModified()` and `getHeaderFieldDate("last-modified", 0)`
always return a result.
Fixes gh-38204
When an interrupted that calls FileChannel.read, the channel is
closed and the read fails with a ClosedByInterruptException. The
closure of the channel makes it unusable by other threads. To
allow other threads to read from the data block, this commit
recreates the FileChannel when a read fails on an interrupted
thread with a ClosedByInterruptException. The exception is then
rethrown to continue the thread's interruption.
