Consider the following example: try (var executor = Executors. These threads offer compatibility with existing Java code and a seamless migration path to benefit from enhanced performance and resource utilization. Virtual threads offer a more efficient alternative to platform threads, allowing developers to handle a large number of tasks with significantly lower overhead. Platform threads are a one-to-one wrapper over operating system threads, while virtual threads are lightweight implementations provided by the JDK that can run many virtual threads on the same OS thread. With this JEP, Java now has two types of threads: traditional threads, also called platform threads, and virtual threads.

This JEP intends to finalize this feature based on feedback from the previous two rounds of preview: JEP 436, Virtual Threads (Second Preview), delivered in JDK 20 and JEP 425, Virtual Threads (Preview), delivered in JDK 19. Starting with Java 11, Oracle will provide JDK releases under the open source GNU General Public License v2, with the Classpath Exception (GPLv2+CPE), and under a commercial license for those using the Oracle JDK as part of an Oracle product or service, or who do not wish to use open source software. Subject to the conditions of the license, it permits free use for all users even commercial and.

This feature provides virtual threads, lightweight threads that dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications on the Java platform. The NFTC is the license for Oracle JDK 17 and later releases. JEP 444, Virtual Threads, was promoted from Proposed to Target to Targeted status for JDK 21.
