JBoss Fuse 6.2 throws java.lang.NoClassDefFoundError: org/apache/aries/blueprint/reflect/MapMetadataImpl

Issue

When deploying a blueprint bundle that uses the httpj:engine-factory (see example below) I get the following error message.

<httpj:engine-factory bus="cxf">
        <httpj:engine port="${port}" host="${host}">
            <httpj:threadingParameters minThreads="${minThreads}" maxThreads="${maxThreads}"/>
        </httpj:engine>
    </httpj:engine-factory>
