Oh that's interesting!
But how do people know how much memory should an application need?
for example that simple web app that only returns "Hello World", how do I know how much memory is enough?
I think you might need to check minimum hardware requirements depending on the JVM version. For example here is for Java 7 or 8
java.com/en/download/help/sysreq.xml
You can also consult on this guide:
docs.oracle.com/cd/E15523_01/web.1...
Because the app is a hello world, then I would assume that you will need the minimum (say a safe 8mb)
