> A NullPointerException is thrown, if I try to resolve a dependency after I cleared the
cache.
> Steps to reproduce:
> 1. create a ivysettings.xml with a chain including a ibiblio and an updatesite as resolver.
> 2. create a dependency to a artifact that can be found with the ibiblio resolver.
> 3. call ivy retrieve
> actual result:
>  - no dependency is resolved and retrieved and a NullPointerException is thrown
> expected result:
>  - dependency is resolved and retrieved from ibiblio
> See also the attached patch and test case.
