Type: Bug
Resolution: Cannot Reproduce
Priority: Minor
Fix Version/s: None
Affects Version/s: 1.0.0.GA
Component/s: Qpid Dispatch Router
Labels:
None

Target Release:

1.2.0.GA
Steps to Reproduce:

Hide

1) Use default config with the following modification: Set http: yes on the listener.
2) Connect with the Console to the router
3) Delete the listener using the console (Entities tab).
4) The router will crash.

I am setting low priority because the testcase is rather artificial (nobody in their right mind will be deleting the only available listener on the router).
