> Project: Cayenne
> Issue Type: Bug

> Reporter: Stefan S.

> In my case, a lot of warnings labeled "No super entity mapping for
> 'superOEName'" floods the log during Cayenne start-up. The project consists
> of multiple DataMaps, where some object entities in early loaded DataMaps are
> derived from object entities declared in DataMaps loaded later. Although the
> MappingCache is refreshed after all DataMaps are loaded, a cache instance is
> created / accessed while adding DataMaps (see call stack below).
>
> *In Detail:*
> {code:java}
> org.apache.cayenne.map.EntityResolver::addDataMap(...)
> {code}
> checks for duplicated names (checkForDuplicatedNames()), which queries the DB
> entities via
> {code:java}
> EntityResolver::getDbEntity(...)
> {code}
> EntityResolver::getDbEntity(...) resolves the entity from the MappingCache
> instance, which contains only DataMaps loaded so far. The cache tries to
> fully resolve the object entities including their inheritance tree, which is
> not yet available due to DataMaps loaded at a later point in time.
>
> *Resolution Proposal:*
> Decoupling of entity resolution for duplicate name checks during DataMap
> loading from building the cache with fully resolved object entities after all
> DataMaps have been loaded.
