Description

I've defined an annotation module. I define a service and contribute it to the EagerLoad configuration point, but EagerLoad throws a ClassCastException. If I define the contribution in an XML file, it works. The relevant code is included below.

Module
======

package com.praxeon.search.service;

import java.util.Collections;
import java.util.List;

import org.apache.hivemind.annotations.AbstractAnnotatedModule;
import org.apache.hivemind.annotations.definition.Configuration ;
import org.apache.hivemind.annotations.definition.Contribution;
import org.apache.hivemind.annotations.definition.Module;
import org.apache.hivemind.annotations.definition.Service;

import com.praxeon.api.index.IndexHome ;
import com.praxeon.api.index.SegmentHostListener;
import com.praxeon.index.service.StatusQueueSegmentHostListener;

import com.praxeon.sysutils.config.XMLConfiguration;

@Module(id="praxeon.search.annot ")
public class SearchModule extends AbstractAnnotatedModule {

@Configuration(id="QueueName")
public String getQueueName()

{ return XMLConfiguration.getValue("/*/Search/SegmentHostQueue"); }

@Service(id="StatusQueueSegmentHostListener")
public SegmentHostListener getStatusQueueSegmentHostListener()

{ String queueName = configuration("QueueName", String.class ); StatusQueueSegmentHostListener listener = new StatusQueueSegmentHostListener(queueName); service(IndexHome.class).addSegmentHostListener(listener); return listener; }

@Contribution(configurationId="hivemind.EagerLoad")
public List eagerLoad()

{ return Collections.singletonList(service("StatusQueueSegmentHostListener", SegmentHostListener.class )); }

}

Exception
=========

java.lang.ClassCastException: $SegmentHostListener_1161fffc175

XML contribution that works
===========================

<contribution configuration-id="hivemind.EagerLoad">
<load service-id="praxeon.search.annot.StatusQueueSegmentHostListener"/>
</contribution>
