Taming the Bias: Unbiased* Safepoint-Based Stack Walking in JFR
Read OriginalThis technical article details the implementation of unbiased safepoint-based stack walking for Java Flight Recorder (JFR) as described in JEP 518. It explains how cooperative sampling avoids safepoint bias by recording state in signal handlers and walking stacks at safepoints, making the process safer and more efficient than the current JFR sampler.
