[cas-dev] method resolvePrincipal of Interface CredentialsToPrincipleResolver not throwing an Exception?

[Scott Battaglia]

An exception like an IOException is specific to the implementation of the
resolver (not all of them would need to do this).  In addition, any handling
of that exception would only be able to occur within that resolver (as none
of the items that call it assume that resolvers require IO operations).
Anything that couldn't be handled by the resolver is something that most
likely could not be handled at all and thus would be a RuntimeException
(which are generally not declared in the signature as you do not want to
force people to catch something they probably won't be able to handle.
