Pitfalls in JVM and Docker Defaults

First, there are a lot of articles about JVM and container-awareness:

• https://blogs.oracle.com/java-platform-group/java-se-support-for-docker-cpu-and-memory-limits

In this post, I use Java 11, which means the default for garbage collector is supposed to be G1GC! Let's look at the defaults, which are automatically chosen by the JVM depending on memory size and provided CPUs.
