As reported on InfoWorld, Java 22 introduces several new thread-related features. One of the most important is the new ScopedValue syntax for dealing with shared values in multithreaded contexts. Let’s take a look.
ScopedValue is a new way to achieve ThreadLocal-like behavior. Both elements address the need to create data that is safely shared within a single thread but ScopedValue aims for greater simplicity. It is designed to work in tandem with VirtualThreads and the new StructuredTaskScope, which together simplify threading and make it more powerful. As these new features come into regular use, the scoped values feature is intended to address the increased need for managing data-sharing within threads.
