Hi,
Two things:
* Nashorn allows access only to public methods and fields (of exported)
classes only.
* With Java.extend, Nashorn adds public overrides of all non-final
protected methods of the superclass.
ClassLoader.definePackage is non-final protected method.
ClassLoader.defineClass is final protected method.
Hence no override of ClassLoader.defineClass added to generated subclass.

When extending java.lang.ClassLoader, I can't seem to execute defineClass.
Here's my test case showing the issue.
var superLoader = Java.super(new (Java.extend(java.lang.ClassLoader))(){});
// defineClass on the super object doesn't exist for some reason
print("defineClass: " + (superLoader.defineClass !== undefined));
// definePackage is protected, but isn't undefined, so that isn't the issue
print("definePackage: " + (superLoader.definePackage !== undefined));
and here's the output of "java -version":
