ORB.setupPresentationManager() currently makes incorrect attempts to load non-existent classes in the JDK. It also references ORB variables that have never been supported or implemented in the JDK ORB (com.sun.CORBA.ORBDynamicStubFactoryFactoryClass)

It might be worth considering removal of this code. The PresentationManager.StubFactoryFactory will always be an instance of StubFactoryFactoryProxyImpl in the JDK ORB cases.

Unnecessary class loading attemps have cause confusion in the past. See JDK-6497156
