The term 'EJBObject' in this case is not well defined. I assume that you mean
an object on the server that delegates to a pooled instance. Depending on the
server architecture, such an object might or might not exist.

The answer to any such question depends on the server you are dealing with.
But generally, you shouldn't assume that the lifetime of the object reference
held by the client (or the client's view of the entity) has much in common
with the lifetime of objects that are used by the server to process client
requests. In the Sybase EAServer architecture, the client JVM garbage collects
the client's object references, and the server garbage collects (by pooling)
the component instances using user-configurable timeouts.
