Prior to this commit, using a dynamic `CaffeineCacheManager` would rely
on `ConcurrentHashMap#computeIfAbsent` for retrieving and creating cache
instances as needed. It turns out that using this method concurrently
can cause lock contention even when all known cache instances are
instantiated.
This commit avoids using this method if the cache instance already
exists and avoid storing `null` entries in the map. This change reduces
lock contention and the overall HashMap size in the non-dynamic case.

Fixes gh-30085
This commit adds default methods to CachingConfigurer and
JCacheConfigurer and removes the reference to their respective support
classes as they are now irrelevant.

Prior to this commit, Spring's SchedulerFactoryBean always set the
"org.quartz.jobStore.class" property to LocalDataSourceJobStore even if
the user had already specified a custom JobStore implementation via the
Quartz properties file or Properties object, thereby effectively
ignoring the user configuration.
This commit addresses this by configuring Quartz to use Spring's
LocalDataSourceJobStore only if a JobStore has not already been
specified via user configuration.

In order to catch Javadoc errors in the build, we now enable the
`Xwerror` flag for the `javadoc` tool. In addition, we now use
`Xdoclint:syntax` instead of `Xdoclint:none` in order to validate
syntax within our Javadoc.
This commit fixes all resulting Javadoc errors and warnings.
This commit also upgrades to Undertow 2.2.12.Final and fixes the
artifact names for exclusions for the Servlet and annotations APIs.
The incorrect exclusion of the Servlet API resulted in the Servlet API
being on the classpath twice for the javadoc task, which resulted in the
following warnings in previous builds.
javadoc: warning - Multiple sources of package comments found for package "javax.servlet"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.http"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.descriptor"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.annotation"
Closes gh-27480
To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.
Closes gh-27098
Prior to this commit, some tests would belong to the PERFORMANCE
`TestGroup`, while they were not testing for performance but rather
performing functional tests that involve long running operations or
timeouts.
This commit moves those tests to the LONG_RUNNING `TestGroup`.
See gh-24830
Includes deprecation of JdbcUtils.extractDatabaseMetaData(DataSource, String) in favor of the now generified version of extractDatabaseMetaData(DataSource, DatabaseMetaDataCallback).
