This JVM performance challenge has two parts.
Part 1
Force an OutOfMemory runtime error to be thrown when you run the demo-client application using property setting demo.mode=challenge-jvm
If you get this right, it will take about 10 seconds for the error to be thrown in your console after you Run.
HINT: Set the demo.mode property in resources/application.properties
HINT: Set your max JVM heap runtime parameter for the demo-client application to 100 MB. See below for IntelliJ instructions.
Part 2
Explain and fix the OutOfMemory error
HINT: Have a look at java class HeapObjects.java.
Extra Credit
Observe the corrected behavior in your Visual-VM Heap Monitor.
IntelliJ Notes
In IntelliJ, you can set JVM parameters by left clicking the java class DemoClientApplication.java. Select "Modify Run Configuration" to add your JVM arguments. You may need to click on the link "Modify Options" in order to expose the 'VM Options' form field.
