Hello, I'm using Karaf 1.6.0. A blueprint bundle declares something like:
        <reference-list interface="..." availability="optional">
<reference-listener ref="SomeRef" bind-method="addStuff" unbind-method="removeStuff" />
        </reference-list>

When starting the bundle, SomeRef.removeStuff() is called with a null reference.

I use reference lists without problems, but this time the unbind method is called with a null reference when the bundle is started.

Can anybody tell me why do I get a null reference and what is the meaning of this null?

Thanks.
