JDK 28 Finalizes Structured Concurrency
JDK 28 finalizes structured concurrency through JEP 543 after seven preview rounds, with no API changes from JDK 27. Developers on JDK 27 can adopt it by removing --enable-preview and recompiling, while code from JDK 25 or 26 may need updates for exception handling and the timeout joiner callback.
