In constructors in the Java programming language, allow statements
that do not reference the instance being created to appear before an
explicit constructor invocation (i.e. super()).
In constructors in the Java programming language, allow statements to
appear before an explicit constructor invocation, i.e., super(..) or
this(..). The statements cannot reference the instance under
construction, but they can initialize its fields. Initializing fields
before invoking another constructor makes a class more reliable when
methods are overridden.

This was introduced as a preview language feature

Primitive Types in Patterns, instanceof, and switch
===================================================
https://openjdk.org/jeps/455
Enhance the Java programming language with string templates. String
templates complement Java's existing string literals and text blocks
by coupling literal text with embedded expressions and template
processors to produce specialized results.
Enhance pattern matching by allowing primitive type patterns in all
pattern contexts, and extend instanceof and switch to work with all
primitive types.

Module Import Declarations

Enhance the Java programming language with the ability to succinctly
import all of the packages exported by a module. This simplifies the
reuse of modular libraries, but does not require the importing code to
be in a module itself.

DEPRECATIONS

Deprecate the Memory-Access Methods in sun.misc.Unsafe for Removal
==================================================================
https://openjdk.org/jeps/471
Deprecate the memory-access methods in sun.misc.Unsafe for removal in
a future release. These unsupported methods have been superseded by
standard APIs, namely the VarHandle API (JEP 193, OpenJDK 9) and the
Foreign Function & Memory API (JEP 454, OpenJDK 22). We strongly
encourage library developers to migrate from sun.misc.Unsafe to
supported replacements, so that applications can migrate smoothly to
modern JDK releases.
