This work is done during so-called safepoints. There are two types of safepoints: local and global. This allows the JVM to do activities like method deoptimizations or stop-the-world garbage collections, where the amount of concurrency should be limited. But how do they actually work? This talk covers the implementation of global and local safepoints in the OpenJDK Speaker: Johannes Bechberger, Track: Free Java devroom, Room: UB5.132, When: Saturday 3 February 2024, 17:50–18:05 (Brussels time), Schedule: FOSDEM 2024 event page, Slides & links Slides, Blog Post, OpenJDK, Licence: Creative Commons Attribution 2.0 Belgium (CC BY 2.0 BE) (as stated in the FOSDEM video archive).
