The same class has not the same classloader

Hi Liste,

First I like to say thank you for all the nice examples.

After a quick good start I ran into problems.
I have written a program that changes the extended class of a class. This is my code:

JavaClass java_class = Repository.lookupClass("de.sagd.xmldb.DebugResource");
java_class.setSuperclassName(resource.getClass().getName());

byte[] bytes = java_class.getBytes();
ClassLoader classloader = new org.apache.bcel.util.ClassLoader();
Class cl = classloader.loadClass("de.sagd.xmldb.$$BCEL$$" + Utility.encode(bytes, true));

Constructor constructor = cl.getConstructor(new Class[] {Resource.class});

The last line throws a java.lang.NoSuchMethodException. 
I found out that:
cl.getConstructors()[0].getParameterTypes()[0].getClassLoader() has the value org.apache.bcel.util.ClassLoader and org.xmldb.api.base.Resource.class.getClassLoader() has the value sun.misc.Launcher$AppClassLoader.

But both of the classes are of type org.xmldb.api.base.Resource.
I tested my code with 5.1 and the SVN Version.

Any hint would be a big help.

Thanks in advance 
Philipp
