Attempt to locate implementation of persistence interface can fail to find metadata

Created: 23/Feb/11 05:37 PM   Updated: 04/Oct/12 05:02 PM   Resolved: 23/Feb/11 05:52 PM
Component/s: Persistence
Affects Version/s: None
Fix Version/s: 3.0.0.m2

 Description  « Hide
If you try to locate an implementation of a persistent interface it can call through to (rdbms) LocateRequest and this tries to get the metadata for the owner of the table (the implementation of the persistent interface). This calls to MetaDataManager.getMetaDataForClass(className) but the class cannot be instantiated (since presumably in a different loader).

We should just check the cache of loaded metadata and return it if present

SVN trunk has this, and should improve performance slightly
