As a bit of trivia, Jakarta EL was originally Unified EL, which was
originally JSP EL, which was originally SPEL.
SPEL: Simplest Possible Expression Language
SpEL: Spring Expression Language
So one could say that SPEL inspired SpEL.
If multiple request mapping annotations are discovered, Spring MVC and
Spring WebFlux now log a warning similar to the following (without
newlines).
Multiple @RequestMapping annotations found on
void org.example.MyController.put(), but only the first will be used:
[
@org.springframework.web.bind.annotation.PutMapping(consumes={}, headers={}, name="", params={}, path={"/put"}, produces={}, value={"/put"}),
@org.springframework.web.bind.annotation.PostMapping(consumes={}, headers={}, name="", params={}, path={"/put"}, produces={}, value={"/put"})
]

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
Prior to this commit, the `DefaultScheduledTaskObservationConvention`
would fail as it tried to add a `KeyValue` to the observation context
that is `null`. This is rejected by the observation registry and should
be prevented. This happened when registered scheduled methods were
lambdas or part of anonymous classes. Those types do not have a
canonical name and return `null` as a value there.
This commit ensures that for these cases, the default convetion uses a
`"ANONYMOUS"` value as the `"code.namespace"` keyvalue.
Fixes gh-31918
