I don't think so, no; but you could write your own such method easily enough, yes? Just load a HashMap with the right answers (like theMap.put(int.class, Integer.class) and then just do theMap.get(int.class) to find the right answer.

I am making new web MVC architecture, where model object's functionality is defined by java 1.5's metadata functionality, and i used cglib to do some modification for these classes at runtime, but i had some problems with cglib/metadata directives, so i started to write new dynamic code generation library (top over asm), and i made AOP style after method functionality, and i need to got correct wrapper class for method's primitive arguments.
Of course i could debug cglib, but i also wanted to learn java vm stuff, so why not.. =))
I asked this functionality because IF somewhere in future there is new primitive type in java, then i don't have to update my code to support it, and still there is method "isPrimitive" in java.lang.Class, so i just wonder if there is method to get wrapper.. Of course it isn't big job to change code, but still i want to do thing's right if there is possibility for it.. =)
