Description

Suppose we have a simple schema consisting of class A and class B, where A is the parent of class B.
Suppose also that we have a simple ruby console program that, upon having the obj_props callback called by the broker, ignores all objects not of class A. For any objects of class A, it prints out the instance (of class A) and all corresponding child instances (of class B).

In the case where managed_connections is enabled in the session, if the agent connected to the broker before the console, then the session.objects method fails to return any objects. The agent can be running for a large length of time before the console connects, and other consoles that connected can see all the published qmf objects, but the console that connected after the agent cannot see the objects.

Finally, I tried writing a simple console that extended debug console that queried for objects on user input to try debugging when session.objects() fails. It appears that the console picks up the qmf objects in the schema written by the user before picking up any of the org.apache.* schemas, and that after the console picks up the org.apache.* schemas, then session.objects() works normally.
