This is the implementation of: - JEP 453: Structured Concurrency (Preview) - JEP 446: Scoped Values (Preview)
For the most part, this is just moving code and tests. StructuredTaskScope moves to j.u.concurrent as a preview API, ScopedValue moves to j.lang as a preview API, and module jdk.incubator.concurrent has been removed. The significant API changes since incubator are: - StructuredTaskScope.fork returns Subtask instead of Future (JEP 453 has a section on this) - ScopedValue.where methods are replaced with runWhere, callWhere and getWhere ------------- Commit messages: - Test should not be in update for main line - Sync with loom repo - Sync up tests frmo loom repo - Sync up with loom repo - Sync update API/impl/tests - Merge - Sync up with loom repo - Merge - Initial commit Changes: https://git.openjdk.org/jdk/pull/13932/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=13932&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8306647 Stats: 9389 lines in 42 files changed: 4995 ins; 4330 del; 64 mod Patch: https://git.openjdk.org/jdk/pull/13932.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/13932/head:pull/13932 PR: https://git.openjdk.org/jdk/pull/13932
