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.
This commit improves PersistenceManagedTypesBeanRegistrationAotProcessor
so that it does not attempt to load JPA classes when checking for the
presence of a PersistenceManagedTypes bean. To make it more clear a
check on the presence for JPA has been added to prevent the nested
classes to be loaded regardless of the presence of the bean.
Closes gh-32155
To improve consistency and avoid confusion regarding primitive types
and their wrapper types, this commit ensures that we always use class
literals for primitive types.
For example, instead of using the `Void.TYPE` constant, we now
consistently use `void.class`.
Prior to this commit, SpEL's Indexer incorrectly requested conversion
to wrappers instead of primitives when setting an element in a
primitive array.
This commit addresses this by requesting primitive conversion -- for
example, conversion to `int.class` instead of `Integer.class` when
setting a value in an `int[]` array.
For greater clarity, this commit also switches from using `TYPE`
constants in wrapper classes to primitive class literals -- for
example, from `Integer.TYPE` to `int.class`.
