Prior to this commit, when using RowCallbackHandler or ResultSetExtractor in JdbcClient
and passing a parameter to paramSource(), an exception was thrown stating "No value
supplied for the SQL parameter 'xxxxxx'" because the SqlParameterSource used internally
was the wrong one.

Prior to this commit, `DispatcherServlet` would completely reset the
response (status, headers and body) before handling errors within Spring
MVC. This can cause unintended consequences when Servlet Filters added
response headers before the error happened. Such response headers might
be still required in case of error handling.
This commit changes the complete reset of the response to only resetting
the response buffer, if possible.

Prior to this commit, it was unclear to users and third parties that it
is necessary to manually configure a StandardTypeLocator with a
specific ClassLoader to ensure that the SpEL expression parser is able
to reliably locate user types.
For example, the StandardBeanExpressionResolver in the spring-context
module configures a StandardTypeLocator using the bean ClassLoader of
the corresponding BeanFactory.
This commit improves the documentation to raise awareness of this fact.

gh-30810 introduced explicit support for collections and maps in
ObjectUtils.nullSafeConciseToString() by invoking isEmpty() on a Map or
Collection to determine which concise string representation should be
used. However, this caused a regression in which an exception was
thrown if the Map or Collection was a proxy generated by
AbstractFactoryBean to support <util:set />, <util:list />, and
<util:map /> in XML configuration.
This commit addresses this set of regressions by always returning
"[...]" or "{...}" for a Collection or Map, respectively, disregarding
whether the map is empty or not.
Closes gh-31138
This commit prints a log message at debug level without
a stacktrace for TypeNotPresentException and uses
warn level instead of error level for other exceptions
since the processing of such bean will just be skipped.
Closes gh-31147
When a handler method is annotated with `@ResponseStatus(reason="...")`,
Spring MVC will use `HttpServletResponse#sendError` to complete the
response. As a result, the Servlet container will send an HTML error
page and any existing data in the response buffer will be cleared.
This commit clarifies the `@ResponseStatus` Javadoc and ensures that a
message is logged at the WARN level if a handler method is annotated
like this and still returns a non-Void value. In this case, the return
value will be ignored and developers should be aware of this fact.

This commit revises the FilePatternResourceHintsRegistrar API and
introduces List<String> overrides of various var-args methods used with
the new builder API.
