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.

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:
