Update Java profiler library to 1.40.0 by jbachorik · Pull Request #10926 · DataDog/dd-trace-java

jbachorik · 2026-03-22T19:08:45Z

What Does This Do

Bumps Java profiler (ddprof-java) to 1.40.0

Motivation

Java 26 compatibility [https://github.com/DataDog/java-profiler/pull/428]
Stability with wasmtime lib [https://github.com/DataDog/java-profiler/pull/420]
Improved stackawalking performance [https://github.com/DataDog/java-profiler/pull/423]

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

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.

Contains a number of stability and performance fixes as well as improved stack unwinding fidelity.
