Runtime Architecture• The byte-code is in fact translated into native
code by a just-in-time compiler.
• The source and the changes are not necessary for interpreting the byte-code, this is just for the development. Normally they are removed for deployment.
• An application can be delivered as some byte-code files that will be executed with a VM. The development image is stripped to remove the unnecessary development components.
