Prior to this commit, if null values were supplied for the
RepeatableContainers or AnnotationFilter arguments to `from()` factory
methods in MergedAnnotations, certain operations would eventually
result in a NullPointerException. This is to be expected; however, the
NullPointerException is often swallowed and only logged at INFO level
with an exception message similar to the following.
> Failed to introspect annotations on org.example.MyClass: NullPointerException
In such cases, the INFO log message is not helpful in diagnosing the
problem. Furthermore, since the exception is swallowed, the desired
operation (e.g., MergedAnnotations.stream(...)) simply returns no
results.
This commit improves the user experience by eagerly asserting non-null
preconditions for required arguments in MergedAnnotations.from()
factory methods.

This commit removes the previously deprecated classes in Spring
Framework 5.2.x. By doing so, Spring Framework now requires RSocket
1.0+.
Closes gh-25548
Since Spring Framework 5.2, @RestControllerAdvice registered with
MockMvc when using MockMvcBuilders.standaloneSetup() has no longer been
properly supported if annotation attributes were declared in the
@RestControllerAdvice annotation. Prior to 5.2, this was not an issue.
The cause for this regression is two-fold.
1. Commit 50c257794f refactored
DefaultListableBeanFactory so that findAnnotationOnBean() supports
merged annotations; however, that commit did not refactor
StaticListableBeanFactory#findAnnotationOnBean() to support merged
annotations.
2. Commit 978adbdae7 refactored
ControllerAdviceBean so that a merged @ControllerAdvice annotation
is only looked up via ApplicationContext#findAnnotationOnBean().
The latter relies on the fact that findAnnotationOnBean() supports
merged annotations (e.g., @RestControllerAdvice as a merged instance of
@ControllerAdvice). Behind the scenes, MockMvcBuilders.standaloneSetup()
creates a StubWebApplicationContext which internally uses a
StubBeanFactory which extends StaticListableBeanFactory. Consequently,
since the implementation of findAnnotationOnBean() in
StaticListableBeanFactory was not updated to support merged annotations
like it was in DefaultListableBeanFactory, we only see this regression
with the standalone MockMvc support and not with MockMvc support for an
existing WebApplicationContext or with standard Spring applications
using an ApplicationContext that uses DefaultListableBeanFactory.
This commit fixes this regression by supporting merged annotations in
StaticListableBeanFactory#findAnnotationOnBean() as well.
Closes gh-25520
This commit removes support for a standalone "L" in the
day-of-week of a cron expression, which used a locale-dependent
API to determine what the last day of the week is (Saturday or
Sunday ?).
Alternatively, we could have implement this in the exact way as Quartz
has done (i.e. treat the "L" like "SAT"), but we opted not to do that,
as having an explicit SAT or SUN is much clearer.
This commit makes sure that in CronExpression, the asterisk is only used
in a range field, and is not surrounded by unexpected characters.
Closes gh-19500
Prior to this commit, StaticListableBeanFactory.isSingleton() returned
false for singleton beans unless they were created by a FactoryBean.
StaticListableBeanFactory.isSingleton() now properly returns true for
all beans not created by a FactoryBean.
Closes gh-25522
This commit introduces support for Quartz-specific features in
CronExpression. This includes support for "L", "W", and "#".
