Remove experimental jvmti wallclock profiler#10872

zhengyu123 · 2026-03-17T14:03:21Z

What Does This Do

Remove profiling.experimental.ddprof.wall.jvmti flag, as it is no longer supported.

Motivation

There are a few issues with the JVMTI-based wall-clock profiler that have limited its adoption:

Between capturing threads for profiling and processing them, some threads may exit, leading to race conditions and making the profiler prone to crashes.
There is no robust mechanism for propagating context, which reduces its overall usefulness.

Additional Notes

Contributor Checklist

Format the title according to the contribution guidelines
Assign the type: and (comp: or inst:) labels in addition to any other useful labels
Avoid using close, fix, or any linking keywords when referencing an issue
Use solves instead, and assign the PR milestone to the issue
Update the CODEOWNERS file on source file addition, migration, or deletion
Update public documentation with any new configuration flags or behaviors

Jira ticket: PROF-14004

Note: Once your PR is ready to merge, add it to the merge queue by commenting /merge. /merge -c cancels the queue request. /merge -f --reason "reason" skips all merge queue checks; please use this judiciously, as some checks do not run at the PR-level. For more information, see this doc.
