cacheConfiguration for Infinispan Index Storage doesn't find configuration file from classpath

Currently it can only find the cache configuration file from relative/absolute path from file system, it doesn't match the documentation and other similar part in the configuration (e.g. storage) which says:

"The name of the Infinispan configuration file for creating a new cache manager. If a file could not be found (on the thread context classloader, on the application's classpath, or on the system classpath), then the name is assumed to reference an existing Infinispan CacheContainer instance via a valid JNDI name or as the name of a service as defined by the local environment. If no such container is found, then the cache container used by the 'storage' configuration is used."
