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.

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.

Add a `NestedFileSystemProvider` implementation so that the JDK's
`ZipFileSystem` can load content from nested jars and nested
directory entries.
Creating a `ZipFileSystem` may be a relatively expensive operation as
zip structures need to be parsed and in the case of directory entries
a virtual datablock nees to be generated on the fly. As such, we
install the `ZipFileSystem` as late as possible since in a typical
application it may never be needed.
This commit also tweaks Gradle and Maven plugins to ensure that the
service loader file is written to repackaged jars.
Closes gh-7161
Update Gradle and Maven plugins to write an empty `META-INF/BOOT.SF`
file whenever there is a nested signed jar.
This update allows Oracle Java 17 to correctly verify the nested JARs.
The file is required because `JarVerifier` has code roughly equivalent
to:
if (!jarManifestNameChecked && SharedSecrets
.getJavaUtilZipFileAccess().getManifestName(jf, true) == null) {
throw new JarException("The JCE Provider " + jarURL.toString() +
" is not signed.");
}
The `SharedSecrets.getJavaUtilZipFileAccess().getManifestName(jf, true)`
call ends up in `ZipFile.getManifestName(onlyIfSignatureRelatedFiles)`
which is a private method that we cannot override in our `NestedJarFile`
subclass. By writing an empty `.SF` file we ensure that the `Manifest`
is always returned because there are always "signature related files".
Fixes gh-28837
Rewrite nested jar code to better align with the implementations
provided in Java 17. This update makes two fundamental changes to
the previous implementation:
- Resource cleanup is now handled using the `java.lang.ref.Cleaner`
- Jar URLs now use the form `jar:nested:/my.jar/!nested.jar!/entry`
Unlike the previous `jar:jar:/my,jar!/nested.jar!/entry` URL format,
the new format is compatible with Java's default Jar URL handler.
Specifically, it now only uses a single `jar:` prefix and it no longer
includes multiple `!/` separators.
In addition to the changes above, many of the ancillary classes have
also been refactored and updated to create cleaner APIs.
Closes gh-37668
Create alternative launcher classes under the package
`org.springframework.boot.loader.launch` and use them in favor
of the previous location.
This update is designed to improve compatibility with future
changes in the loader.
Closes gh-37667
