Understanding JVM Memory Layout with OpenJDK24's New PrintMemoryMapAtExit VM Option

Sat, 27 Jul 2024 10:38:31 +0000

OpenJDK24 recently added a new HotSpot JVM option called PrintMemoryMapAtExit.

I know this because I’m the maintainer of a project called VMOptionsExplorer, whose job is to track changes to the more than 2000 command line options you can use to control the Java Virtual Machine (JVM).

VMOptionsExplorer presents this information as a searchable online dictionary of VM options available at https://chriswhocodes.com

and also on Foojay at https://foojay.io/command-line-arguments/ (although the Foojay copy doesn’t always cover the latest JDKs).
