[jboss-user] [Javassist user questions] - attempted duplicate class definition for name:

[Michenux]

Hi,

I would like to know it is possible to modify
a class that has been already loaded.

My test case :
MyClass myClass = new MyClass();
  | ClassPool pool = ClassPool.getDefault();
  | CtClass cc = pool.get("MyClass");
  | //make some changes
  | cc.toClass();

It faults with :
Caused by: java.lang.LinkageError: loader (instance of  sun/misc/Launcher$AppClassLoader): attempted  duplicate class definition for name: "MyClass"
