The OpenJDK Quality Group promotes the testing of FOSS projects with OpenJDK early-access builds as a way to improve the overall quality of the release. This heads-up is part of a Quality Outreach update sent to the projects involved. To learn more about the program and how to join, please check the Quality Outreach wiki page.
New Early Access builds of Generational ZGC are now available at jdk.java.net/genzgc.
Changes include :
Rebased on top of jdk-20+21
Added macOS builds
Heuristics rewritten to deal with a problematic case where Generational ZGC spent too much focus on doing young generation collection when it's more beneficial to spend resources to collect the old generation.
GC logging rewritten to easier see what log lines belong to what collection / generation, plus many additional changes that should make it easier to read and understand GC logs
Barrier elision enhanced to remove barriers from array access of newly allocated arrays
Enhanced the generated hs_err crash text file
Fixed and unified code quality and style
Proper feedback on these EA builds should be sent to the zgc-dev mailing list.
