org.apache.sling.commons.classloader.DynamicClassLoaderManager
The dynamic class loader manager is a central service managing all dynamic class loaders. It provides a class loader that can be used by bundles requiring access to all publically available classes. The default implementation uses the package admin service to load classes and resources. Keep in mind, that the class loader might get invalid. This happens for example, if the class loader loaded a class from a bundle which has been updated in the meantime. Or a dynamic class loader provider has changed. In these cases, the dynamic class loader manager service is unregistered and reregistered again, so you should discard your classloader and invalidate loaded objects whenever this happens.

            // make sure to cleanup any existing class loader
            this.destroyRepositoryClassLoader();


            // get the dynamic class loader for the bundle using this
            // class loader writer
            final DynamicClassLoaderManager dclm = (DynamicClassLoaderManager) this.callerBundle.getBundleContext().getService(
                this.dynamicClassLoaderManager);


            this.repositoryClassLoader = new RepositoryClassLoader(
                    this.classPath,
                    this,
                    dclm.getDynamicClassLoader());
        }
        return this.repositoryClassLoader;
