Description

As discussed on the ML, we should store the hash code of AccessibleObjectDescriptor in a private member variable after it has been computed the first time. The computed value can be returned on subsequent invocations. Since AccessibleObjectDescriptor is immutable (all of its fields are final) the hash code can never change, once an AccessibleObjectDescriptor has been initialized.
