> Environment: Ubuntu 2.6.32-25-generic-pae,
> java version "1.6.0_26"

> 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.
