A Guide to @Locked in Lombok

Project Lombok's @Locked annotation, introduced in version 1.18.32, is designed to enhance support for virtual threads in Java by acting as a variant of the ReentrantLock, ensuring better performance in concurrent applications. It simplifies the locking mechanism in methods, reducing boilerplate code, and provides a clear advantage over the @Synchronized annotation, particularly with virtual threads. Multiple methods can share the same lock, or different locks can be specified for read and write operations to boost performance.
