Java and Memory ProtectionsJava and Memory ProtectionsPosted Nov 22, 2006 14:49 UTC (Wed) by NAR (subscriber, #1313)In reply to: Java and Memory Protections by smitty_one_each Parent article: Virtual Machines and Memory Protections Isn't dynamic code generation a natural consequence of a virtual machine coupled with reflection? I'm not sure - in my mind, reflection is about getting runtime information about the objects, it has nothing to do with creating anything. Anyway, as far as I understand, the problem with memory protection is not simply the dynamic code generation, but the compilation of the generated code to machine-level instructions. So even though one can write self-modifing code in LISP or perl, it's not a problem until the interpreter executes this code, not the CPU directly.
