    JetBrains Runtime

    JetBrains Runtime

    Runtime environment based on OpenJDK for running IntelliJ products

    JetBrainsRuntime is the custom Java Runtime Environment (JRE) distribution maintained by JetBrains that enhances the standard OpenJDK to better support JetBrains products and provide a robust, optimized runtime for IDEs like IntelliJ IDEA, Rider, and other tools. It includes performance-tuned garbage collectors, desktop integration fixes, font rendering improvements, enhanced GTK support on Linux, and additional patches not available in stock JDK builds to ensure smoother, more stable behavior for large-scale IDE usage. These modifications are aimed at reducing resource consumption, improving windowing and high-DPI rendering, and delivering a consistent user experience across operating systems. By controlling the runtime environment, JetBrains can ship their IDEs with confidence that core JVM behavior will align with expected performance, reducing platform-specific issues and enhancing responsiveness.

    Wheefun Properties Library for Java

    A java library for binding runtime properties

    This library allows for the programmer to bind arbitrary properties to types which can be accessed at runtime via reflection. Properties can be declared via annotation and later manipulated through a simple static interface; no special naming conventions are required and the properties can be bound to any method which has the appropriate signature.
