Hi all, Is someone knows why package sun.reflect.generics is so complex ?

Because it was written by Gilad ;-)

This package (and subpackage) it used to reify a generics signatures to a java.lang.reflect.Type tree. It creates a parser, parse the signature to create an AST, and use a visitor to create the tree.

This package, contains in my opinion, lot of unecessary garbage. - It creates an AST even if the Type tree can be created in one pass. - A bunch of interfaces has only one implementation like Visitor. - Use a visitor even if there is only one operation. - Use lots of generics can be removed because only one instanciation is used.

While the code is a bit elaborate compared to the minimum needed for the task at hand, I think it is otherwise well-structured and there are no plans to refactor it. -Joe
