This commit refines the preDetermineBeanTypes algorithm that AOT uses
to approximate the order of preInstantiateSingletons more closely.
Previously, the algorithm assumed that all beans where non-lazy
singletons in terms of initialization order, which led to inconsistent
order in CGLIB proxy generation.
We now explicitly park lazy beans so that their types are determined
during a second phase, matching the order of regular initialization
order.

Previously, if a factory method is defined on a parent, the generated
code would blindly use the method's declaring class for both the target
of the generated code, and the signature of the method.
This commit improves the resolution by considering the factory metadata
in the BeanDefinition.
Closes gh-32609
This change improves the message of several parsing-related exceptions
that would previously entirely swallow the original exception's message
and sometimes have a slightly misleading message as a result.
This is done by appending the cause's `toString` representation to the
IllegalArgumentException messages instead of an hardcoded "cause".
Closes gh-32636
This commit fixes an issue where a Cacheable method which returns a
Flux (or multi-value publisher) will be invoked once, but the returned
publisher is actually subscribed twice.
The previous fix 988f3630c would cause the cached elements to depend on
the first usage pattern / request pattern, which is likely to be too
confusing to users. This fix reintroduces the notion of exhausting the
original Flux by having a second subscriber dedicated to that, but uses
`refCount(2)` to ensure that the original `Flux` returned by the cached
method is still only subscribed once.
Closes gh-32370
This commit fixes an issue where a Cacheable method which returns a
Flux (or multi-value publisher) will be invoked once, but the returned
publisher is actually subscribed twice.
By using the Reactor `tap` operator, we ensure that we can emit values
downstream AND accumulate emitted values into the List with a single
subscription.
The SignalListener additionally handles scenarios involving cancel,
for instance in case of a `take(1)` in the chain. In that case values
emitted up until that point will have been stored into the List buffer,
so we can still put it in the cache. In case of error, no caching occurs
and the internal buffer is cleared. This implementation also protects
against competing onComplete/onError signals and cancel signals.
Closes gh-32370
Schedulers remain strict, just plain executors are lenient on shutdown now.
An early shutdown for executors can be enforced via setStrictEarlyShutdown.
Closes gh-32226
This commit introduces support for a Spring property named
`spring.context.expression.maxLength`. When set, the value of that
property is used internally in StandardBeanExpressionResolver to
configure the SpelParserConfiguration used when evaluating String
values in bean definitions, @Value, etc.
Closes gh-31952
This change moves container element properties from ParameterErrors
to base class ParameterValidationResult, and makes that support
independent of whether violations are nested within a container
element bean or through constraints on container elements, e.g.
`List<@NotBlank String>`.
Closes gh-31887
This is able to resolve the original method even if no bridge method has been generated at the same class hierarchy level (a known difference between the Eclipse compiler and regular javac).
Closes gh-21843
To align with the existing processInjection() method in
AutowiredAnnotationBeanPostProcessor, this commit introduces an analogous
method in CommonAnnotationBeanPostProcessor.
Closes gh-31956
