Class Constructor problem

[Abdullah Odeh Al-Zaghameem <ao...@yahoo.com>]

Hi all,
 
I am working on a model that weave some code in classes bytecode at load-time. I face the following problem regarding the class constructor!! :
 
I tried first to modify the type of the constructor argument by using [setArgumentType], but i got a strange response!!!!; i.e. after saving back the bytecode and browsing it using some java-decompilers, the constructor's parameter type is still the same as the old one, at the new source code, BUT it was changed in the constant pool!!. (the <init> signature is changed) I found no mental explanation for that tell now.
 
Then, I tried to add a new constructor!! using BCEL, but I fail; I don't know if that because BCEL doesn't has the suitable APIs to do that, or its illigal to do such thing!!.
 
Any comments and ideas will be appreciated so much.
Thanks,
A. O .Z
