camel pipeline does not copy over properties

I created a camel pipeline using the following command in MyRouteBuilder.java

from("jbi:service:.....pipeline")
.pipeline("jbi:endpoint:....endpoint1",
"jbi:endpoint:...endpoint2",
"jbi:endpoint:..endpoint3"
);
}

In my first endpoint, I set several Properties (I set the same property several places: exchange.getProperty, exchange.getMessage("in").setProperty and exchange.getMessage("out").setProperty).

None of these properties gets propagated to the next steps in the pipeline.
