> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 2.7.0
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 2.8.0
>
>
> When Camel lookup in the registry, it may lookup in different runtime
> registries, such as OSGi blueprint. If an explicit type has been provided as
> a parameter you will get a ClassCastException if the type does not match. But
> you cannot see which types was a stake. So we should provide a better
> exception.
> Caused by: java.lang.ClassCastException
