> 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.
