All current testing for structured concurrency passes in JDK20. Will keep monitoring the JEP's state periodically.

Are all tests re-enabled?

Are all tests re-enabled?

Yes. References:

• JDK20: https://github.com/adoptium/aqa-tests/blob/master/openjdk/excludes/ProblemList_openjdk20-openj9.txt
• JDK21: https://github.com/adoptium/aqa-tests/blob/master/openjdk/excludes/ProblemList_openjdk21-openj9.txt

Only one RI specific test is disabled, StructuredThreadDumpTest (#15278), since it cannot be supported with OpenJ9.

Current tests in JDK20: https://github.com/ibmruntimes/openj9-openjdk-jdk20/tree/openj9/test/jdk/jdk/incubator/concurrent/StructuredTaskScope

re #17487 (comment): The last disabled structured concurrency OpenJDK/jtreg test was enabled through #17709.

Closing since all OpenJDK/jtreg tests for structured concurrency pass and have been enabled.
