The second early access build of JXInsight/OpenCore 6.5 has been published on our developer [protected] site. This build introduces the first of a number of new probe classification metering extensions that label probes (methods) based on runtime call flow analysis. The boundary metering extension classifies probes based on call boundary analysis. Probes that represent a root or entry point are given a ingress label. Probes that completed without any nested metering of other probes within their thread execution scope are given a egress label. Probes not representing an entry or exit point are given a transit label.
