Historically, @Configuration classes that did not declare @Bean
methods were allowed to be abstract. However, the changes made in
76a6b9ea79 introduced a regression that prevents such classes from
being abstract, resulting in a BeanInstantiationException. This change
in behavior is caused by the fact that such a @Configuration class is
no longer replaced by a concrete subclass created dynamically by CGLIB.
This commit restores support for abstract @Configuration classes
without @Bean methods by modifying the "no enhancement required" check
in ConfigurationClassParser.

To help with AOT support, update AbstractHttpServiceRegistrar to store
HTTP Service types by name, and avoid loading classes during the bean
definition registration phase.

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, the Test Bean Override feature provided support
for overriding beans based on qualifier annotations in several
scenarios; however, qualifier annotations got lost if they were
declared on the return type of the @Bean method for the bean being
overridden and the @BeanOverride (such as @MockitoBean) was based on
a supertype of that return type.
To address that, this commit sets the @BeanOverride field as the
"qualified element" in the RootBeanDefinition to ensure that qualifier
annotations are available for subsequent autowiring candidate
resolution.

This commit updates the tests of property values code generated to
invoke the generated code from a `static` context. This ensures that
the test fails if that's not the case.
This commit also updated LinkedHashMap handling that did suffer from
that problem.
Closes gh-34659
This commit introduces a new ResponseSpec.awaitEntityOrNull() extension
function to replace ResponseSpec.toEntity(...).awaitFirstOrNull() and
pass the CoroutineContext to the CoExchangeFilterFunction.
CoroutineContext propagation is implemented via ReactorContext and
ClientRequest attribute.

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+.
Closes gh-33616
Now that we are using JDK 18+ (currently JDK 24 -- see JavaConventions
in buildSrc for details), we can reinstate links to JUnit 5 Javadoc APIs.
