Java Addon V10 is a comprehensive extension framework designed to integrate seamlessly with modern Java Runtime Environments (JRE). Unlike traditional plugin systems that require heavy boilerplate code and deep inheritance hierarchies, V10 leverages modern Java features—such as enhanced modules, pattern matching, and virtual threads—to offer a lightweight, decoupled architecture.

The addon fails to attach to a running JVM. Solution: Ensure you are running the same user as the target JVM. On Linux, you may need to run sudo jattach or disable ptrace restrictions. v10 includes a diagnostic script ( addon-diag.sh ) to fix permissions automatically.

Gone are the complex XML or manual registry configurations. V10 relies entirely on standard Java annotations and ServiceLoader mechanics. Defining an extension point is now as simple as adding a single @AddonExtension annotation. Core Features of Java Addon V10
