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).

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
Update `ClassFileClassMetadata` so that member classes only include
immediate children. This aligns with the other `ClassMetadata`
implementations.
Closes gh-34869
Update `ClassFileClassMetadata` to align the behavior of
`getSuperClassName()` with other readers in that it returns
`null` for `package-info` classes.

This commit introduces a new constructor for CompositePropertySource
that accepts a `String name` and an Iterable<PropertySource<?>>, which
allows a CompositePropertySource to be constructed from existing
property sources, such as an instance of MutablePropertySources.

Includes spring.locking.strict revision to differentiate between true, false, not set.
Includes checkFlag accessor on SpringProperties, also used in StatementCreatorUtils.

- ClassUtils.isAssignable(): Avoid Map lookup when the type is not a
primitive.
- AnnotationsScanner: Perform low cost array length check before String
comparisons.
- BeanFactoryUtils: Use char comparison instead of String comparison.
The bean factory prefix is '&', so we can use a char comparison
instead of more heavyweight String.startsWith("&").
- AbstractBeanFactory.getMergedBeanDefinition(): Perform the low cost
check first. Map lookup, while cheap, is still more expensive than
instanceof.

This commit adds another optimization mainly for the use case where
there is no encoded sequence, and updates the Javadoc of both
StringUtils#uriDecode and UriUtils#decode to match the implementation.
Closes gh-34673
Refine the StringUtils#uriDecode method in the following ways:
- Use a StringBuilder instead of ByteArrayOutputStream, and only decode
%-encoded sequences.
- Use HexFormat.fromHexDigits to decode hex sequences.
- Decode to a byte array that is only allocated if encoded sequences are
encountered.

We have had an ObjectToOptionalConverter since Spring Framework 4.1;
however, prior to this commit we did not have a standard Converter for
the inverse (Optional to Object).
To address that, this commit introduces an OptionalToObjectConverter
that unwraps an Optional, using the ConversionService to convert the
object contained in the Optional (potentially null) to the target type.
This allows for conversions such as the following.
- Optional.empty() -> null
- Optional.of(42) with Integer target -> 42
- Optional.of(42) with String target -> "42"
- Optional.of(42) with Optional<String> target -> Optional.of("42")
The OptionalToObjectConverter is also registered by default in
DefaultConversionService, alongside the existing
ObjectToOptionalConverter.

Prior to this commit, Spring Framework would use its own ASM fork to
read class/method/annotation metadata from bytecode. This is typically
used in configuration class parsing to build bean definitions without
actually loading classes at runtime at that step.
This commit adds support for a new metadata reading implementation that
uses the ClassFile API available as of Java 24. For now, this is turned
on by default for Java 24+.
