Any developer worth its salt should worry how their application 
makes use of the available resources.

The JVM is just a possible implementation of Java, the language.

It was quite an unfortunate decision for the Sun marketing team 
to call the language and the VM the same name.

This always ends up in lots of confusions when people consider 
the JVM to be the only way to execute Java.

Usually only developers with compiler design background end up 
making the difference, as languages and implementations are quite 
two different issues.
