Blueprint bundle with camel-dozer endpoint waiting for namespace handlers [http://dozer.sourceforge.net]

Issue

I have a blueprint bundle with camel-dozer endpoint:

<camelContext xmlns="http://camel.apache.org/schema/blueprint">
    <endpoint uri="dozer:xml2java?mappingFile=transformation.xml&amp;targetModel=org.apache.camel.component.dozer.example.xyz.XYZOrder&amp;sourceModel=org.apache.camel.component.dozer.example.abc.ABCOrder" id="xml2java"/>
    <route>
        <from uri="direct:start"/>
        <to ref="xml2java"/>
        <to uri="mock:result"/>
    </route>
</camelContext>

However, when I tried to deploy it, the bundle was never getting deployed. Instead, it was simply waiting for namespace handlers [http://dozer.sourceforge.net] even though I had already had camel-dozer feature installed:
