public class BundleClassLoader
extends java.lang.ClassLoader

This is a delegating class loader. It always delegates to OSGi bundle's class loader. ClassLoader.defineClass() is never called in the context of this class. There will never be a class for which getClassLoader() would return this class loader. It overrides loadClass(), getResource() and getResources() as opposed to their findXYZ() equivalents so that the OSGi export control mechanism is enforced even for classes and resources available in the system/boot class loader.
