After the bootstrap phase (and with spring.locking.strict=true during the bootstrap phase), getSingletonFactoryBeanForTypeCheck always locks. In a background bootstrap thread, it never locks. Otherwise, it tries locking and explicitly resolves the bean class for subsequent type-based resolution (even for a component-scanned class) when it fails to acquire the lock. Furthermore, getObjectFromFactoryBean follows the same locking algorithm for post-processing.

- Jackson2JsonEncoder to JacksonJsonEncoder
- Jackson2JsonDecoder to JacksonJsonDecoder
- Jackson2SmileEncoder to JacksonSmileEncoder
- Jackson2ObjectMapperBuilder to JsonMapper and XmlMapper
- MappingJackson2JsonView to JacksonJsonView
- MappingJackson2HttpMessageConverter to JacksonJsonHttpMessageConverter
- MappingJackson2XmlHttpMessageConverter to JacksonXmlHttpMessageConverter
NonClosingInputStream extends FilterInputStream, which does not forward some
newer InputStream methods such as transferTo and readAllBytes. Specific InputStream
implementations may have more optimized methods (e.g., FileInputStream).

This commit introduces RequestBodyAdvice#determineReadHints and
ResponseBodyAdvice#determineWriteHints in order to be able to support
SmartHttpMessageConverter hints, as well as related `@JsonView`
support.

This commit introduces Jackson 3 based variants of the following
Jackson 2 classes (and related dependent classes).
MappingJackson2JsonView -> JacksonJsonView

This commit introduces Jackson 3 SmartHttpMessageConverter based
variants of the following Jackson 2 classes (and related dependent classes).
org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter ->
org.springframework.http.converter.AbstractJacksonHttpMessageConverter
MappingJackson2HttpMessageConverter -> JacksonJsonHttpMessageConverter
MappingJackson2SmileHttpMessageConverter -> JacksonSmileHttpMessageConverter
MappingJackson2CborHttpMessageConverter -> JacksonCborHttpMessageConverter
MappingJackson2XmlHttpMessageConverter -> JacksonXmlHttpMessageConverter
MappingJackson2YamlHttpMessageConverter -> JacksonYamlHttpMessageConverter
They use hints instead of MappingJacksonValue and MappingJacksonInputMessage
to support `@JsonView` and FilterProvider.
Jackson 3 support is configured if found in the classpath otherwise
fallback to Jackson 2.
JacksonHandlerInstantiator needs to be enabled explicitly if needed.

Spring Framework 6.2 introduced support for an escape character for
property placeholders (by default '\'). However, as of Spring Framework
6.2.6, there was no way to either escape the escape character or disable
escape character support.
For example, given a `username` property configured with the value of
`Jane.Smith` and a `DOMAIN\${username}` configuration string, property
placeholder replacement used to result in `DOMAIN\Jane.Smith` prior to
6.2 but now results in `DOMAIN${username}`. Similarly, an attempt to
escape the escape character via `DOMAIN\\${username}` results in
`DOMAIN\${username}`.
In theory, one should be able to disable use of an escape character
altogether, and that is currently possible by invoking
setEscapeCharacter(null) on AbstractPropertyResolver and
PlaceholderConfigurerSupport (the superclass of
PropertySourcesPlaceholderConfigurer).
However, in reality, there are two hurdles.
- As of 6.2.6, an invocation of setEscapeCharacter(null) on a
PropertySourcesPlaceholderConfigurer applied to its internal
top-level PropertySourcesPropertyResolver but not to any nested
PropertySourcesPropertyResolver, which means that the `null` escape
character could not be effectively applied.
- Users may not have an easy way to explicitly set the escape character
to `null` for a PropertyResolver or
PropertySourcesPlaceholderConfigurer. For example, Spring Boot
auto-configures a PropertySourcesPlaceholderConfigurer with the
default escape character enabled.
This first issue above has recently been addressed by gh-34861.
This commit therefore addresses the second issue as follows.
- To allow developers to easily revert to the pre-6.2 behavior without
changes to code or configuration strings, this commit introduces a
`spring.placeholder.escapeCharacter.default` property for use with
SpringProperties which globally sets the default escape character that
is automatically configured in AbstractPropertyResolver and
PlaceholderConfigurerSupport.
- Setting the property to an empty string sets the default escape
character to `null`, effectively disabling the default support for
escape characters.
spring.placeholder.escapeCharacter.default =
- Setting the property to any other character sets the default escape
character to that specific character.
spring.placeholder.escapeCharacter.default = ~
- Setting the property to a string containing more than one character
results in an exception.
- Developers are still able to configure an explicit escape character
in AbstractPropertyResolver and PlaceholderConfigurerSupport if they
choose to do so.
- Third-party components that wish to rely on the same feature can
invoke AbstractPropertyResolver.getDefaultEscapeCharacter() to obtain
the globally configured default escape character.

Prior to this commit, the new `ClassFileAnnotationMetadata` would fail
when reading `Class<T>` annotation attributes when values are primitive
types.
This commit uses `java.lang.constant.ClassDesc` to better parse type
descriptors from the bytecode.
Fixes gh-24882
PropertyPlaceholderConfigurer and PreferencesPlaceholderConfigurer have
been officially deprecated since Spring Framework 5.2.
Since we no longer expect applications to depend on these outdated
mechanisms, this commit deprecates these classes "for removal" in
Spring Framework 8.0.
