Enclosing class:

OSGiServiceDiscoverer

public class OSGiServiceDiscoverer.ClassLoaderImpl
extends java.security.SecureClassLoader

This class loader provides resource access to META-INF/services/... which is used by many frameworks. OSGi Import-Package and DynmaicImport-Package headers do not support split packages. Another option is to use Require-Bundle header. We can collect the list of bundles and add them as required bundles to a special gateway bundle.
