JEP proposed to target JDK 21: 453: Structured Concurrency (Preview)

[Mark Reinhold]

The following JEP is proposed to target JDK 21:

  453: Structured Concurrency (Preview)
       https://openjdk.org/jeps/453

  Summary: Simplify concurrent programming by introducing an API for
  structured concurrency.  Structured concurrency treats groups of
  related tasks running in different threads as a single unit of work,
  thereby streamlining error handling and cancellation, improving
  reliability, and enhancing observability.  This is a preview API.

Feedback on this proposal from JDK Project Committers and Reviewers [1]
is more than welcome, as are reasoned objections.  If no such objections
are raised by 23:59 UTC on Tuesday, 6 June, or if they’re raised and
then satisfactorily answered, then per the JEP 2.0 process proposal [2]
I’ll target this JEP to JDK 21.
