While working on ISPN-3350, I tried using a store and loader configuration value for my cache.

<local-cache name="local">
    <store class="org.infinispan.loaders.file.SingleFileCacheStore"/>
</local-cache>

However when starting the server I am met with the following error and the cache is not started properly:

The error stems from the fact that the LegacyStoreConfiguration is used for caches that only provide the classname and not configuration. I am not certain if this is a fix solely in the server or would need some additional changes in Infinispan core. Also maybe there is some other configuration needed? If so the schema should have a requirement for the field or have it more clearly shown in exception.
