IBM's Liberty Profile as both - a standalone product and the base for Websphere Application Server. IBM uses it as it's default runtime when hosting Apps in their BlueMix Cloud Platform (based on Cloud Foundry).

Unfortunately Magnolia will always throw a RuntimeException ("Magnolia is not configured properly and therefore unable to start: real path can't be obtained...") when starting up the system on Liberty.

Caution: make sure to deploy as exploded war - else ServletContext#getRealPath(String) will always return <null> (see the spec)
