The Java Virtual Machine is a marvel of modern technology, and arguably the biggest asset that Oracle acquired when buying Sun. But have you ever thought about the small miracles that happen when you use it?
We will give you an appreciation of this VM by going into the compilation process and how bytecode is interpreted, visit some of the levels of optimization, and take a look at the garbage collector. To top it all of, we'll have a short detour to the Dalvik VM, and show how its constraints lead to different tradeoffs.
Outline:
how a stack-based VM works in general
compiling & some bytecode
optimizations at compile- and at runtime
garbage collection
the Dalvik VM
This is a lot of content for one talk; I intend to just skim some of the highlights and create some appreciation of the JVM.
