Java 11 Features
Additional Java EE Modules Removed
Additional Java EE Modules Removed from Java 11 Java 11 continued the trend of removing Java EE (Enterprise Edition) modules from the JDK, which started in earlier versions (like Java 9 and Java 10). This was a significant shift in Java’s ecosystem as it marked the end of the official inclusion of Java EE technologies …
Enhanced Deprecation
Java 11, released in September 2018, brought a number of improvements and enhancements to the language and platform. One of the notable changes was the enhanced deprecation mechanism, which aims to improve how deprecated features are handled in Java. Deprecation in Java is a way for developers to mark certain features or APIs as outdated …
Time-Based Release Versioning
Time-Based Release Versioning in Java 11 Java 11 introduced a major change in how Java versions are released, moving to a time-based release versioning system. This means that instead of waiting for major new features to be ready, Java now follows a fixed release schedule, where new versions of Java are released every six months. …
Low-Overhead Heap Profiling
In modern software applications, especially large and long-running Java programs, memory management is critical.Poor memory usage can lead to performance degradation, OutOfMemoryErrors, and even application crashes.Heap profiling — the process of analyzing memory usage patterns — helps developers understand, optimize, and debug how memory is allocated and used. However, traditional heap profiling tools often introduce …
Enhanced Security with TLS 1.3
In today’s connected world, security over the internet has become more crucial than ever. Sensitive data such as passwords, financial transactions, and personal communications must be protected from prying eyes.Transport Layer Security (TLS) is the backbone of secure communication on the internet.With the release of TLS 1.3 in 2018 — and support added in Java …
ChaCha20 and Poly1305 Cryptographic Algorithms
Cryptography is an essential pillar of modern software development. With rising concerns around privacy, data breaches, and secure communications, it has become increasingly important to use fast, reliable, and secure encryption algorithms.In Java 11, two powerful cryptographic algorithms — ChaCha20 and Poly1305 — were officially introduced. These algorithms provide developers with the ability to perform …
JDK Flight Recorder Event Streaming
Modern software systems, especially those built with Java, are often deployed in complex, dynamic environments where performance monitoring and troubleshooting are critical. Over the years, the Java ecosystem has evolved various tools to assist developers and system administrators in diagnosing performance issues with minimal impact on running applications. One of the most significant advancements in …
Flight Recorder
Java Flight Recorder (JFR) is an integrated profiling and diagnostics tool in the Java Virtual Machine (JVM), designed to monitor and analyze Java applications with minimal performance impact. With Java 11, JFR became open-sourced in OpenJDK, eliminating the need for commercial licenses and making it widely accessible for developers. This essay briefly explores JFR’s significance, …
