How To Find Default Configuration (e.g. -Xmx, -Xms) Settings (ergonomics) for JVM?

JVM comes with "ergonomics" feature which tries to find the best possible JVM configuration for the execution environment.

The configuration choices suggested by JVM can be printed with:

java -XX:+PrintFlagsFinal

A fraction of the output for Java 8:


uintx MaxHeapSize                              := 4294967296                          {product}   
uintx InitialHeapSize                          := 268435456                           {product}
bool UseG1GC                                   = false                               {product}
