OpenJ9

OpenJ9 is an open-source software component called a Java Virtual Machine (JVM), which runs Java applications. It acts as a bridge between your computer's hardware and Java programs, translating instructions so they can execute efficiently. OpenJ9 is designed to optimize performance, reduce memory use, and start up quickly, making Java applications run faster and more efficiently. It’s used in various environments, from servers to desktops, and is favored for its ability to improve the responsiveness and resource management of Java-based software.
