Class ClassClassPath

java.lang.Object
javassist.ClassClassPath
All Implemented Interfaces:
ClassPath
public class ClassClassPath extends Object implements ClassPath
A search-path for obtaining a class file by getResourceAsStream() in java.lang.Class.

Try adding a ClassClassPath when a program is running with a user-defined class loader and any class files are not found with the default ClassPool. For example, 

 ClassPool cp = ClassPool.getDefault();
 cp.insertClassPath(new ClassClassPath(this.getClass()));
This code snippet permanently adds a ClassClassPath to the default ClassPool. Note that the default ClassPool is a singleton. The added ClassClassPath uses a class object representing the class including the code snippet above.

Class files in a named module are private to that module. This method cannot obtain class files in named modules.
