Yes, and if you use internal jars, whose packages you don't export, then you
can't place those classes into your APIs/SPIs as ClassCastException will
happen when the client bundle tries to assign them to other namespaced
classes, e.g.
String classname = Abc.class.getName();
ServiceReference ref = context.getServiceReference( classname );
if( ref != null )
{
Abc abc = (Abc) context.getService( ref );
}
will give you a ClassCastException even though the ref is holding a Abc
instance, but in different classloader namespace.
