JEP 533 on structured concurrency is technically deep but Java-specific.
Summary
JEP 533, integrated for JDK 27, tightens exception handling in Structured Concurrency: join() now throws ExecutionException instead of FailedException for the three standard joiners, aligning with Future.get(). A third type parameter R_X on StructuredTaskScope and Joiner gives custom joiners precise checked-exception contracts, and a new open overload pairs the default join policy with a UnaryOperator for configuration.
