NPE Accesing Service During Bringup
-----------------------------------
Key: AXIS2-3497
URL: https://issues.apache.org/jira/browse/AXIS2-3497
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: deployment, transports
Affects Versions: 1.3
Environment: Linux Fedora Core 4, Geronimo 1.0, JRE 1.5.0_12
Reporter: Al Ski
Priority: Blocker
We have a web service that is brought up in a Geronimo / Jetty container. If
there is a client trying to access the service endpoint as the service is being
brought up, we see:

The service endpoint then fails to come online even though the admin
application shows it as active. Deactivating and reactivating the service
doesn't bring the service up either. If you access the service endpoint you get:
<soapenv:Reason xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope";>
<soapenv:Text xml:lang="en-US">The service cannot be found for the endpoint
reference (EPR) /rmf/services/RevaManagementService</soapenv:Text>
</soapenv:Reason>
The client is a single threaded client making a "ping" type request looking for
the service which never comes online.
