JDK-8351557	21.0.8	Andreas Steiner	P4	Resolved	Fixed	master

Analysts and supporters often use /proc/xx/maps to make sense of the memory footprint of a process.

Interpreting the memory map correctly can help when used as a complement to other tools (e.g. NMT). There even exist tools out there that attempt to annotate the process memory map with JVM information.

That, however, can be much more easily and accurately done within the JVM. At least for mappings originating from hotspots, we have the relevant information in NMT.
