Hi all,

I'm trying to test the latest svn with spring inside the aar via
startUp() . This was working a few days ago with startUp() in the
Service interface. Anyways, ServiceLifeCycle seems to work by
reflection so I have a services.xml like so:

<serviceGroup>
  <service name="SpringInit">
    <description>
        This is a sample spring init service
    </description>
    <parameter name="ServiceClass" locked="false">spring.SpringInit</parameter>
    <operation name="springInit">
        <messageReceiver
class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>
    </operation>
  </service>
  <service name="SpringAwareService">
    <description>
         simple spring example - inside the AAR
    </description>
    <!-- need the TCCL param when using spring inside the AAR -->
    <parameter name="ServiceTCCL" locked="false">composite</parameter>
    <parameter name="ServiceObjectSupplier"
locked="false">org.apache.axis2.extensions.spring.receivers.SpringAppContextAwareObjectSupplier</parameter>
    <parameter name="SpringBeanName"
locked="false">springAwareService</parameter>
    <operation name="getValue">
        <messageReceiver
class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>
    </operation>
  </service>
</serviceGroup>

So the idea is that spring.SpringInit implements ServiceLifeCycle and
will load the spring config via startUp() . And not until a client
invokation the MR of SpringAwareService will be called.

What I'm seeing though is the SpringAwareService MR is being called on
server start, even though I have not declared any scope. And
ServiceLifeCycle.startUp() is not called ever. The MR was never
invoked on server start before with the default scope IIRC. This is
generating a stack trace on server start as :
