alt Hacker NewsThat would place significant limitations on the applications that can be compiled. As the JEP explains: “Features such as dynamic class loading, dynamic linkage, dynamic dispatch, and dynamic reflection bring vast expressive power, and have been fundamental to the platform's success. HotSpot handles these features naturally, while static compilers struggle with them. Even heroic amounts of static analysis cannot make up for the fact that these features require many decisions to be made at run time. Implementors of static compilers for Java code have therefore resorted to incompatible constraints, such as closed-world assumptions, and to putting significant burdens on developers, such as having to identify in advance the classes eligible for reflection.”
Therefore I don’t see AOT-only becoming an integral part of standard Java in the foreseeable future.

we are not talking about fully supporting dynamic loading, because it's not needed in all the cases, and in some cases, the list of allowed classes in the application can (or must) be limited.
i guess what i am saying is that AOT-only case is not "standard java", but something that will make a (more) useful replacement for things like c/c++.
It works pretty well for greenfield projects on .NET, so long as you can live without third-party libraries that don't support AOT.
Existing code bases can be a pain, though, especially applications that heavily rely on things like C++/CLI and COM Interop that basically need to be rewritten from scratch.
Which is not to say that it's intended to replace the traditional JIT runtime in applications where it isn't troublesome, because it's not.
