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.

Previously, when lazy initialization was enabled, STOMP-based WebSocket
messaging would not work as the stompWebSocketHandlerMapping bean was
not initialized and CONNECT requests would go unanswered.
This commit adds a LazyInitializationExcludeFilter that causes the
stompWebSocketHandlerMapping bean to always be initialized eagerly.
This triggers initialization of the WebSocket transport allowing
requests to be received and processed.

Restore the `getUseRelativeRedirects` method with a `Boolean` object
result and introduce `isUseRelativeRedirects` for the primitive boolean
variant.
See gh-20796
Prior to this commit, the property was a Boolean with a null default.
If it was explicitly set by the user, a context customizer would use
that value to set it on the context. However, if it was not set, the default
wouldn't be tomcat's default but `false` because it was explicitly set to
`false` in `TomcatServletWebServerFactory`. This commit defaults the property
itself to `false` so that the default is more obvious to the user.
Fixes gh-20796
This commit upgrades to RSocket 1.0.0-RC7.
This new RC brings API changes we have to adapt to. As of this commit,
we're introducing a new `RSocketServerCustomizer` which replaces the now
deprecated `ServerRSocketFactoryProcessor`.
Closes gh-21046
Refine `DataSourceAutoConfiguration` conditions so that an empty
`spring.datasource.url` property can be used to enable the embedded
source.
Fixed gh-20996
Previously, a condition checked the value of "spring.datasource.url" to
determine if an embedded database has to be created as a fallback. When
the value is set with an unresolved placeholder, this fails even if
the DataSource is going to created by another mean ultimately.
This commit makes a more conservative check by only checking the
presence of the property rather than its value.
Closes gh-20438
