>             Project: Infinispan
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 7.1.0.Final
>            Reporter: Sanne Grinovero
>             Fix For: 8.2.0.Beta2
>
>
> This is easy to reproduce: start a {{CacheManager}} which has a {{Transport}} configured with a non-existent resource name for the JGroups configuration.
> Would be great to have a better error message.
