dex2jar doesn't preserve method argument names, only types.

[Google Code Exporter]

What steps will reproduce the problem?
1. Use dex-reader with a class visitor


What is the expected output? What do you see instead?
I want to see besides the argument types, the names of the arguments

What version of the product are you using? On what operating system?
Latest

Please upload the file which cause the issue if possible.
Any class

Please provide any additional information below.
I tried other software that processed DEX files and they do provide the method 
argument names, and they are not auto generated, but exactly the method names I 
gave them when I wrote my code. So it's not something that is not available 
inside the dex file, but something dex2jar doesn't implement. Would be great to 
have implemented, since it makes reading/decompiling code much more pleasant.

Just passing by.... 

Class files can store the names of arguments. In fact, there is a command line 
parameter to java compiler to force it to preserve them.

However, in reality I don't think you can extract the names of method 
parameters. Why do compiled java class files need to store it? At least in 
release versions (without debug information) of classes most likely it will be 
without method parameter names.
