Issue Description

Issue	Description
JDK-8313083	Print 'rss' and 'cache' As Part of the Container Information The HotSpot runtime code has been updated to additionally print a container's 'rss' and 'cache'. The additional output can be found in the JVM's response to a "jcmd [PID] VM.info" request and in the `hs_err` file generated in case of JVM abrupt termination. This will help monitoring and troubleshooting OutOfMemory situations as OOM killer can terminate a process if its `rss` + `cache` usage reaches the max memory limit of the container.

Print 'rss' and 'cache' As Part of the Container Information

The HotSpot runtime code has been updated to additionally print a container's 'rss' and 'cache'. The additional output can be found in the JVM's response to a "jcmd [PID] VM.info" request and in the hs_err file generated in case of JVM abrupt termination.

This will help monitoring and troubleshooting OutOfMemory situations as OOM killer can terminate a process if its rss + cache usage reaches the max memory limit of the container.
