Description

The property :

	public void setIndexIterable(Iterable<IndexProvider> indexIterable) {
		this.indexIterable = indexIterable;
	}

The implementation :

public class ListIndexIterable implements Iterable<IndexProvider>

The Blueprint :

    <bean id="listIndexIterable" class="org.neo4j.kernel.ListIndexIterable">
    	<property name="indexProviders">
    		<reference-list interface="org.neo4j.graphdb.index.IndexProvider"
				availability="optional"/>
    	</property>
    </bean>
    <bean id="graphDatabaseFactory" class="org.neo4j.kernel.DefaultGraphDatabaseFactory">
    	<property name="indexIterable" ref="listIndexIterable"/>
    </bean>

Expected result : works because ListIndexIterable implements Iterable<IndexProvider>

Actual result :

Caused by: java.lang.Exception: Unable to convert value org.neo4j.kernel.ListIndexIterable@674df816 to type java.lang.Iterable<org.neo4j.graphdb.index.IndexProvider>
