This commit augment the AOT section with best practices we have
experienced while working on the AOT engine. In particular, it describes
how a FactoryBean with an unresolved generic should be handled.
Closes gh-30434
This commit adds support for MethodHandles in SpEL, using the same
syntax as user-defined functions (which also covers reflective Methods).
The most benefit is expected with handles that capture a static method
with no arguments, or with fully bound handles (where all the arguments
have been bound, including a target instance as first bound argument
if necessary). Partially bound MethodHandle should also be supported.
A best effort approach is taken to detect varargs as there is no API
support to determine if an argument is a vararg or an explicit array,
unlike with Method. Argument conversions are also applied. Finally,
array repacking is not always necessary with varargs so it is only
performed when the vararg is the sole argument to the invoked method.

This commit improves both the javadoc and the reference guide section on
the Elvis SpEL operator to clarify that in addition to `null` objects,
empty Strings also lead the operator to evaluate to its second operand.
The reference guide's advanced snippet is modified to use such an empty
String instead of `null` to make that behavior prominent with some code.
See gh-30318
Closes gh-30352
Updated the Spring Framework documentation to include an example of using Vavr's Try monad to trigger transaction rollbacks when a @Transactional-annotated method returns a Failure. The modified documentation demonstrates how to use Try in a transactional method and how to check if an exception has been wrapped inside a Try.Failure instance. Additionally, a link to the official Vavr documentation was added to provide more information on the Try method.
This commit adds an `anchor-rewrite.properties` file in the reference
documentation sources. This allows to redirect from one anchor to
another when they are renamed.
This also populates the file with anchors that were renamed in the AOT
section of the documentation.
Closes gh-30132
