Prior to this commit, the `RequestPredicates` would add new attributes
to the existing request attributes by creating a new `LinkedHashMap`
with the total number of elements as its new initial capacity.
This would not achieve optimal performance as initial resize or rehash
operations could be expected. Consistently using
`CollectionUtils#newLinkedHashMap` avoids this problem.

ServletAttributesMap inherited default implementations of the size
and isEmpty methods from AbstractMap which delegates to the Set returned
by entrySet. ServletAttributesMap's entrySet method made this fairly
expensive, since it would copy the attributes to a List, then use a
Stream to build the Set. To avoid the cost, add implementations of
isEmpty / size that don't need to call entrySet at all.
Additionally, change entrySet to return a Set view that simply lazily
delegates to the underlying servlet request for iteration.
Closes gh-32189
This commit ensures that, when creating a RestClient.Builder from a
RestTemplate, the UriBuilderFactory is only copied if it has been
changed from the default values.
Before this commit, the UriBuilderFactory was effectively alway copied,
resulting in not being able to use a baseUrl.
This commit also introduces a small memory optimization in
DefaultUriBuilderFactory, so that default environment variables are
created lazily.

This commit replaces occurrences of modelAttribitePredicate with modelAttributePredicate
in HandlerMethodValidationException and the associated validator.

As a bit of trivia, Jakarta EL was originally Unified EL, which was
originally JSP EL, which was originally SPEL.
SPEL: Simplest Possible Expression Language
SpEL: Spring Expression Language
So one could say that SPEL inspired SpEL.
This commit introduces a globally applied Checkstyle rule which
enforces the use of class literals for primitive types and void by
forbidding the use of the TYPE constants in Boolean, Character, Byte,
Short, Integer, Long, Float, Double, and Void.
For example, if MyClass uses one of the TYPE constants, the build will
now fail with a message similar to the following.
[ERROR] <...>/MyClass.java:39: Please use class literals for primitives and void -- for example, int.class instead of Integer.TYPE.
