Provide more control over factory failure handling
Allow flexible constructor arguments in factory implementations
Closes gh-28057
Add an additional `FactoryInstantiationFailureHandler` strategy
interface to `SpringFactoriesLoader` to allows instantiation
failures to be handled on a per-factory bases.
For example, to log trace messages for only factories that can't
be created the following can be used:
FactoryInstantiationFailureHandler.logging(logger);
If no `FactoryInstantiationFailureHandler` instance is supplied
then `FactoryInstantiationFailureHandler.throwing()` is used
which provides back-compatible behavior by throwing an
`IllegalArgumentException`.

Update `SpringFactoriesLoader` so that factory implementation classes
can have a constructor with arguments that are resolved dynamically.
Arguments are resolved using a `ArgumentResolver` interface that is
passed to the `loadFactories` method. This strategy interface is
intentionally simple and only allows resolution based on the argument
type. A number of convenience methods are provided to allow resolvers
to be built. For example:
ArgumentResolver.of(String.class, "tests")
.and(Integer.class, 123);
Factory implementation classes must have a non-ambiguous constructor
in order to be instantiated. The `SpringFactoriesLoader` uses the same
algorithm as `BeanUtils.getResolvableConstructor`.

Since the Nashorn JavaScript engine was removed in Java 15, these tests
will never be run on a Java 17+ JDK which is required as of Spring
Framework 6.0.

Since Spring Framework 5.3, BeanUtils.copyProperties() honors generics
in the source and target property types (see gh-24187); however, this
refinement of the contract was not properly documented prior to this
commit. In addition, the refinement can be a breaking change for users
who were relying on the previous unreliable behavior.
This commit therefore clarifies the behavior for generics support in
BeanUtils.copyProperties() and introduces a table of example matches
and mismatches when generics are involved.
Closes gh-27259
This commit updates InitDestroyBeanPostProcessor so that it contributes
init or destroy method names to the `RootBeanDefinition`. This is then
used by the generator to provide these methods to the optimized AOT
context.
Invocation of those init methods still happen using reflection so
dedicated hints are contributed for them.
Closes gh-28151
This commit makes sure that the response returned by coroutine handler
methods that return ResponseEntity<Flux> is unwrapped correctly.
Closes gh-27809
This commit updates InjectionGenerator to request a resolved attribute
with a dedicated type if multiple methods with the same name and the
same number of arguments exist. This was previously done already for
constructors and this commit harmonizes the algorithms to methods as
well
Closes gh-28154
This commit updates the generator to stop specifying a field type when
reflection is necessary, or when a reference to a field should be
retrieved as its name alone suffices.
This could trigger package protected issues if the field type is not
public.
See gh-28047
This commit fixes the algorithm used to analyze a generic parameter. If
a type in the generic signature is protected, the type is return rather
than the full signature. This makes sure that the appropriate package
is used. Previously, it would have incorrectly used the type of the
raw class.
Using a generic type for such a use case is wrong, and ProtectedElement
has been updated to expose a `Class` rather than a `ResolvableType`.

This commit introduces a way to process a GenericApplicationContext
ahead of time. Components that can contribute in that phase are
invoked, and their contributions are recorded in the
GeneratedTypeContext.
This commit also expands BeanFactoryContribution so that it can exclude
bean definitions that are no longer required.
Closes gh-28150
This commit adds a way to refresh a GenericApplicationContext for ahead
of time processing: refreshForAotProcessing() processes the bean factory
up to a point where it is about to create bean instances.
MergedBeanDefinitionPostProcessor implementations are the only bean
post processors that are invoked during this phase.
Closes gh-28065
This commit adds a way for a BeanFactoryPostProcessor to participate to
AOT optimizations by contributing code that replaces its runtime
behaviour.
ConfigurationClassPostProcessor does implement this new interface and
computes a mapping of the ImportAware configuration classes. The mapping
is generated for latter reuse by ImportAwareAotBeanPostProcessor.
Closes gh-2811
