Subject [jira] [Created] (QPID-6685) ServerScopedRuntimeExceptions occurring during the Broker's initial open phase are ignored,
Date Sun, 09 Aug 2015 07:53:47 GMT
Keith Wall created QPID-6685:
--------------------------------

             Summary: ServerScopedRuntimeExceptions occurring during the Broker's initial
open phase are ignored, 
                 Key: QPID-6685
                 URL: https://issues.apache.org/jira/browse/QPID-6685
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
            Reporter: Keith Wall
             Fix For: qpid-java-6.0


ServerScopedRuntimeExceptions are thrown in situations where the Broker must cause itself
to shutdown immediately as no reasonable recovery exists.  Currently ServerScopedRuntimeExceptions
occurring during the Broker's initial open phase are swallowed without causing the 'open'
to fail.

For example, HttpManagement throws a SSRE if its port is occupied.  If you create this situation
using netcat and start the Broker, one can see that Broker continues despite the SSRE.

{code}
 nc -46l 8080 &
./bin/qpid-server &
{code}

Notice the absence of HTTP is bound in the startup messages:

The logs show the SSRE exception, but the Broker effectively ignores it and comes up anyhow:
