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

The same setup produces the follow NPE in 1.4.1

> It's difficult to provide a simple testcase for this as I've only seen it in our large modular build system and it's sensitive to things like the order of the dependencies. 
> The modules use the following configurations
>    <conf name="default"   extends="package" transitive="true"/>
>    <conf name="compile"   extends="default" visibility="private" transitive="false"/>
>    <conf name="runtime"   extends="default" visibility="public"  transitive="true"/>
>    <conf name="test"      extends="runtime" transitive="true"/>
> The error occurs when resolving the transitive test conf. 
> Another factor that may or not be relevant is that none of our resolvers have a version in the pattern.
