Java SE Development Kit (JDK) 25.0.2

The Java SE Development Kit (JDK) by Oracle is a comprehensive software development environment designed for building applications, applets, and components using the Java programming language. As the cornerstone of Java development, the JDK provides a robust suite of tools and libraries that cater to both novice and seasoned developers.

At its core, the JDK includes the Java Runtime Environment (JRE), which is essential for running Java applications. It also features a collection of development tools such as the Java compiler (javac), the Java Virtual Machine (JVM), and an extensive set of APIs that facilitate the creation of high-performance, cross-platform applications.

One of the standout features of the JDK is its integrated development environment (IDE) support. It seamlessly integrates with popular IDEs like IntelliJ IDEA, Eclipse, and NetBeans, enhancing the development experience with features like code completion, debugging, and real-time error detection. This integration makes it easier for developers to write, test, and deploy Java applications efficiently.

The JDK also excels in its comprehensive documentation and community support. Oracle provides extensive resources, including tutorials, guides, and a vibrant community forum, which are invaluable for troubleshooting and mastering Java development. The regular updates and long-term support (LTS) versions ensure that developers have access to the latest features and security enhancements, maintaining the reliability and performance of their applications.

Security is a paramount concern in today's development landscape, and the JDK addresses this with robust security features. It includes a wide array of security APIs, tools for key and certificate management, and built-in mechanisms for secure coding practices. This ensures that applications developed using the JDK are resilient against common security threats.

Performance optimization is another area where the JDK shines. The HotSpot JVM, included in the JDK, employs advanced techniques like just-in-time (JIT) compilation and garbage collection to optimize runtime performance. This results in faster execution of Java applications and efficient memory management, making the JDK suitable for both small-scale applications and large, enterprise-level systems.

Moreover, the JDK is designed with cross-platform compatibility in mind. Whether you're developing on Windows, macOS, or Linux, the JDK provides a consistent development environment, ensuring that your Java applications can run seamlessly across different operating systems.

In summary, the Java SE Development Kit (JDK) by Oracle is an indispensable tool for Java developers. Its rich set of features, robust security, performance optimization, and cross-platform compatibility make it a versatile and reliable choice for developing a wide range of Java applications. Whether you're building simple desktop applications or complex enterprise systems, the JDK provides the tools and support you need to succeed in the dynamic world of Java development.

Release notes:

New Release
New Features:
core-libs/java.rmi➜ Endpoint Identification Enabled By Default for RMI Connections Over TLS (JDK-8341496 (not public)):
RMI will use TLS connections if the javax.rmi.ssl.SslRMIClientSocketFactory class is used. These connections now have TLS endpoint identification enabled by default. This may cause some previously-working TLS connections to fail. If this occurs, ensure that the certificate presented by the server has a Subject Alternative Name that matches the server's hostname. Alternatively, endpoint identification for RMI TLS connections can be disabled on the client side by setting the jdk.rmi.ssl.client.enableEndpointIdentification system property to false.
Notable Issues Fixed:
hotspot/gc: -XX:+UseTransparentHugePages Again Enables Transparent Huge Pages for G1 (JDK-8366434):
G1, the default garbage collector, can again properly utilize Transparent Huge Pages (THP) on systems with the THP mode configured as madvise.
The issue preventing the option -XX:+UseTransparentHugePages from enabling THP has been resolved.
Other Notes:
install/install:
Windows Installers to Return to Full Version Directory and Use of Junction (JDK-8310932 (not public))
For the JDK11+ LTS families, the JDK will install into a version-specific installation directory by default. The installation directory of 11+ will have a - before the version-specific string to keep consistency with the past 11+ conventions per family. A junction, also known as a symlink for Windows, will also be created in a "latest" directory.
Bug Fixes:
Unexpected exception in sun.java2d.cmm.lcms.LCMSImageLayout
The ICC_Profile class may throw exceptions during serialization
Enforce limits on the size of an XBM image
java.awt.TextField allows to identify the spaces in a password when double clicked at the starting and end of the text
JFileChooser in GTK L&F still displays HTML filename
LineBorder does not scale correctly
JPasswordField identifies spaces in password via delete shortcuts
Right
