Constructor calls like new AtomicInteger(0) cause a volatile write that
can be saved in cases where the constructor parameter is the default
value.

Previously, the default servlet was registered automatically when using
embedded Jetty, Tomcat, or Undertow. However, it is not used by the
majority of applications where Spring MVC's DispatcherServlet will be
the only servlet that's needed. As such configuring the default servlet
was wasting CPU and memory.
This commit changes the default for registering the default servlet to
false. It can be re-enabled by setting
server.servlet.register-default-servlet=true.
Closes gh-22915
Previously, spring.flyway.init-sqls was only applied to Flyway's
configuration if Flyway was being configured to create the DataSource.
If Flyway was being configured to use an existing DataSource, init-sqls
was not applied. This is a hangover from when the init SQLs support was
introduced. At that time, Flyway only supported SQL to initialize the
connection when it was creating the DataSource. Flyway 5.2 added init
SQL support no matter how Flyway's DataSource was configured.
This commit updates FlywayAutoConfiguration to always apply the
init-sqls property to Flyway's configuration. The property's
documentation does not describe the current limitation so this change
should align the behaviour with what the documentation leads people to
expect.

Refactor `BootstrapRegistry` support following initial prototype work
with the Spring Cloud team.
This update splits the `BootstrapRegistry` API into `BootstrapRegistry`,
`BootstrapContext` and `ConfigurableBootstrapContext` interfaces and
moves it to the same package as `SpringApplication`.
A new `Bootstrapper` interface has been introduced that can be added
to the `SpringApplication` to customize the `BootstrapRegistry` before
it's used.
Closes gh-23326
Remove casting "timestamp" to `java.util.Date` in
`ErrorMvcAutoConfiguration` as the cast is not necessary and it
prevents other types (e.g. `java.time`) from being used.
See gh-23256
Previous to this commit the connection idle timeout and heartbeat
interval were mapped to seconds whereas Cassandra expects ms for all
duration types.
This commit fixes the mapping and removes the default duration unit
since it should be considered ms like every other duration properties.
Closes gh-23249
The commit also includes an upgrade to Nimbus JOSE JWT 9.0. Spring
Security requires 9.0 and it is not backwards compatible with 8.19.
Closes gh-23225
Closes gh-23242
This commit deprecates the
`"spring.resources.chain.html-application-cache"` configuration property
and its support, since the feature has been deprecated in Spring
Framework.
The app-cache manifest feature is being removed from browsers in favor
of web workers.
Closes gh-23228
ReactiveDataAccessStrategy has been deprecated in Spring Data R2BC in
favor of R2dbcConverter (and StatementMapper and UpdateMapper). When
not using Boot, an R2dbcConverter bean is now defined by
AbstractR2dbcConfiguration. This commit updates
R2dbcDataAutoConfiguration to replace the definition of a
ReactiveDataAccessStrategy bean with the definition of an
R2dbcConverter bean.
See gh-23197
Prior to this commit, Spring Boot would auto-configure both
Elasticsearch variants: `RestClient` ("Low Level" client) and
`RestHighLevelClient` ("High Level" client).
Since one can be derived from the other, this would create complex and
unclear situations depending on what developers provided with their
configuration.
`RestHighLevelClient` is mostly for actual use of the Elasticsearch API,
with support for specific methods and (de)serialization. On the other
hand, `RestClient` is merely wrapping the Apache HTTP client for
load-balancing support and low level HTTP features.
This commit completely removes the support for `RestClient` in Spring
Boot and now requires the presence of the
`org.elasticsearch.client:elasticsearch-rest-high-level-client`
dependency for REST client support with Elasticsearch.
Closes gh-22358
This commit adds a protected method that lets an override customize the
configuration of the ClassPathScanningCandidateComponentProvider used
to scan entities.
