--------------------------------------------

Did this solve the issue?
I use the same configuration as you, and I patched activemq-camel 5.3.0 to include your modified header. But when I instanciate a bundle that uses the activemq-camel component, I get the following error:

My bundle's dependencies are:
Import-Package = com.espertech.esper.client;version="3.1",eu.diva.factoryinstdiva,eu.diva.osgi.component,eu.diva.tis.api.alert,eu.diva.tis.api.context,eu.diva.tis.api.dom
ain,eu.diva.tis.context.sensors.temperature,eu.diva.tis.context.sensors.temperature.factory,eu.diva.tis.wildcat.osgi,javax.jms,net.sf.cglib.reflect,org.apache.activemq.camel.component,org.apache.camel;version="2.1.0.SNAPSHOT",org.apache.camel.builder;version="2.1.0.SNAPSHOT",org.apache.camel.model;version="2.1.0.SNAPSHOT",org.apache.camel.osgi,org.osgi.service.log,org.ow2.wildcat;version="2.1",org.slf4j;version="1.5"

And I have camel-jms[2.1.0-SNAPSHOT] installed with the modified activemq-camel and activemq 5.3.0.

> The current pom of the activemq project uses 2.0 as camel version.
> The issue is that when we deploy activemq-camel 5.3.0 top of servicemix 4.1.0-SNAPSHOT, we have a classloading issue because activemq-camel bundle cannot import org.apache.camel.component.jms package from Camel 2.1.SNAPSHOT
> May I propose to change version or add a version range in the MANIFEST file generated for activemq-camel :
> The current is :
