No, it just means Jonathan didn't look hard enough. I found it though.
Last sentence in section 9.5.3.
"After an entity object has been removed, subsequent attempts to access the
entity object by a remote client result in the java.rmi.NoSuchObjectException."
Also check Figure 19 "Client View of Entity Object Life Cycle". It is
also quite clear there.
Also the last sentence in section 9.7.1.
"All references to an entity object that does not exist are invalid. All
attempted invocations on an entity object that does not exist result in
an java.rmi.NoSuchObjectException being thrown."
Also in 10.3.4.1 (second bullet point)
I think that exhausts the requirements. It is 100% clear. The behaviour
that was described of avoiding any checks in ejbLoad is non-compliant
with the spec. It may be useful however as a performance optimization
as long as it doesn't affect the customer's application, which I expect
will often be the case.
