From Camel 2.19.x, the camel-spring-dm feature/bundle has been totally removed, that's why the org.apache.camel.osgi.CamelNamespaceHandler couldn't be found anymore.

http\://camel.apache.org/schema/osgi=org.apache.camel.osgi.CamelNamespaceHandler

There is still definition above in the spring.handlers of the activemq-osgi bundle. this may need to be removed or updated from spring.handlers.
