Prior to this commit, OnClassCondition started a thread even if the number of
passed autoconfiguration class candidates never exceeded 1. This commit only
starts a thread if there is actually work to split in half.

As of Spring Framework 5.3, it is now possible to use `PathPatternParser`
to parse and match request mapping path patterns, as an alternative to
the current default `AntPathMatcher`.
This new implementation has been used for a while in Spring WebFlux and
it’s been designed for consistency and performance.
This commit introduces a new configuration property for opting-in this
new variant:
`spring.mvc.pathmatch.matching-strategy=path_pattern_parser`
The default option is still `ant_path_matcher` for now, but we might
change the default in future versions since Spring Framework considers
it the best choice for modern applications.
There are several behavior differences with this new variant:
* double wildcards `"**"` are rejected when used in the middle patterns,
this is only allowed as the last matching segment in a pattern.
* it is incompatible with some path matching options, like
suffix-pattern, registered-suffix-pattern or configuring a Servlet
prefix on the `DispatcherServlet` (`spring.mvc.servlet.path=/test`)
This commit introduces two `FailureAnalyzer` implementations to guide
developers when facing those issues.
Closes gh-21694
This commit improves the validation of URLs provided in the property
'spring.redis.url' used to auto-configure a Spring Data Redis
connection. In particular, only the URL schemes 'redis://' and
'rediss://' are allowed, and any other scheme will result in a
configuration error. A failure analyzer is also provided to improve
diagnostics for common mis-configurations detected by this validation.
Fixes gh-21999
Previously, the import selector for `@ImportAutoConfiguration` did not
consider the spring.autoconfigure.exclude property when determining
which auto-configurations to exclude. This meant that tests using a
slice that included a particular auto-configuration would include it
even if the application's configuration excluded it via
spring.autoconfigure.exclude. Confusingly, this could result in a
sliced test using an auto-configuration that would be excluded in a
broader `@SpringBootTest`.
This commit updates the ImportAutoConfigurationImportSelector to
consider the spring.autoconfigure.exclude property so that sliced tests
will use a subset of the auto-configurations that a `@SpringBootTest`
would use.
Fixes gh-21736
Since Spring Framework 4.3.0.RC2, a default embedded value resolver
has been registered with the bean factory when one is not otherwise
configured. This meant that placeholders in `@Value` would be resolved
with or without PropertyPlaceholderAutoConfiguration defining a
PropertySourcesPlaceholderConfigurer bean. However, placeholders in
bean definitions would only be resolved if a
PropertySourcesPlaceholderConfigurer was defined.
This commit updates PropertyPlaceholderAutoConfigurationTests to align
with this change in Framework. We now test that placeholders are
resolved in `@Value` annotations with or without the auto-configuration
and that placeholders in bean definitions are only resolved with the
auto-configured.
Closes gh-22230
