Those warnings should only be raised by ModeShape's CMIS webapp which bundles Apache Chemistry which, in turn, brings all these JARs in. There are several topics on similar warnings in AS/EAP (e.g. Class Path entry does not point to a valid jar for Class-Path reference).
As long as the webapp has all the required jars in WEB-INF/lib (which it should), it's safe to ignore those warnings.
Thanks for the confirmation.
