I don't quite understand how can you be in a situation where you don't know
at compile time the exact type of the primitive and therefore know the type
for the correct wrapper (unless you are manipulating bytecode).

You can probably write an overloaded static function that will do this such
as:
Integer getWrapper(int i) { return new Integer(i); }
Long   getWrapper(long l)  { return new Long(l); }
