Hivemind throwing an exception when the service interface is
Regi stryShutdownListener
I'm trying to make a service who's whole job in life is to listen for a
registry shutdown and do something. Here is the hivemodule.xml snip.
<service-point
id="ControllerShutdown"
interface="org.apache.hivemind.events.RegistryShutdownListener">
<invoke-factory>
<construct
class="com.mckesson.lab.adept.ControllerShutdown">
<set-service
property="controller"
service-id="com.mckesson.adept.Controller" />
</construct>
</invoke-factory>
</service-point>
<contribution
configuration-id="hivemind.EagerLoad">
<load
service-id="ControllerShutdown" />
</contribution>
I worked around this problem by making an empty interface and using that for
my service instead of the RegistyShutdownListener interface.
<service-point
id="ControllerShutdown"
interface="com.mckesson.lab.adept.ControllerShutdown">
<invoke-factory>
<construct
class="com.mckesson.lab.adept.ControllerShutdownImpl">
<set-service
property="controller"
service-id="com.mckesson.adept.Controller" />
</construct>
</invoke-factory>
</service-point>
I'm eager loading it and getting the following exception at registry
construction.
