Experimental example code to measure the memory consumption of a Java application, or, the memory consumption of a unit test. Run it with:

mvn test

Here is an example output of mvn test | grep loopCount:

testBaseline1: used=483104, loopCount=0, total=124780544
testBaseline2: used=483760, loopCount=0, total=124780544
