A few weeks ago I faced an interesting problem trying to analyze a memory consumption in my Java application (Spring Boot + Infinispan) running under Docker. The Xmx parameter was set to 256m, but the Docker monitoring tool displayed almost two times more used memory. Below we will try to understand the reasons of such a strange behavior and find out how much memory the app consumed in fact.

Je ne connaissais pas le Native Memory Tracker du jdk8
