AsyncGetStackTrace: The Improved Version Of AsyncGetCallTrace (JEP 435)
FOSDEM 2023

Java profiling relies heavily on the AsyncGetCallTrace API. But this API has major drawbacks: It is unofficial, not well-tested, and omits important information. I propose AsyncGetStackTrace (JEP Candidate 435) as an improved replacement.

This talk will give an overview of AsyncGetCallTrace and AsyncGetStackTrace, their implementations, differences, and use cases.

Speakers: Johannes Bechberger
