How to replace classname in local var declaration?

[deadance]

Hi,

I encountered a problem in trying to replace classname in a class.
Original code looks like:

 public void test()
 {
 String str = new String("123");
 System.out.println(str);
 }

When I apply replaceClassName("java.lang.String", "MyString") on the containing class, I got:

 public void test()
 {
 String str = new MyString("123");
 System.out.println(str);
 }

But I want it to be:

 public void test()
 {
 MyString str = new MyString("123");
 System.out.println(str);
 }

How could I do this with javassist? Thanks!

best,

Hi,

It is a sort of bug of Javassist, but it should not make any real problem since a local variable is not really typed at bytecode level. Your code should run without any problem
although a decompielr may claim the type of a local variable remains the same.

Yes, thanks Chiba. I did work it out and in fact got the decompiler to stop doing it if I removed the debug form the class. It obviously forced it to try and work out the type of the local variable.

Thanks again.
