An exception occurred during a call to a QPid function. Details: Problem rerouting MR.Retry to BOB.Ex. Error code: 1. Error message: No object found with ID=0-0-0--0(org.apache.qpid.broker:queue:MR.Retry)



Version-Release number of selected component (if applicable):
1.3

How reproducible:
100%

Steps to Reproduce:
1. Compile attached code
2. Run
3. When prompted, quickly enter any number and press enter (If a longer time is waited, then no error will occur)
  
Actual results:

An exception occurred during a call to a QPid function. Details: Problem rerouting MR.Retry to BOB.Ex. Error code: 1. Error message: No object found with ID=0-0-0--0(org.apache.qpid.broker:queue:MR.Retry)

Comment 2 Ted Ross 2010-11-18 13:51:18 UTC 
I've identified the source of the problem...  In the broker's embedded agent, newly created objects (in this case queues), are placed on a new-object-list.  When the periodic publish interval arrives, objects on the new-object-list are moved to the main object-list.

The bug is that when method calls are handled, objects addressed are only looked up in the main list.  Objects created since the last interval are not visible to the method handler.

The fix is simple and low-risk... Prior to method handling, the contents of the new-object-list need to be moved to the main object-list.
