Due to the requirements of "full emulation", A Java agent class is required.
Because of Java' s class loading & linking methodology, we can use runtime "Hooks" to implement our Kernel API. In other words, loads an emulated class at development time, and provides another set of classes at runtime. The annotation "fzos.FzOSInternalImplementation" is a mark for implementation differential.
