To ensure that the agent discovers all classes on startup, pass 'jpa-
eager-load' parameter to the agent:
-javaagent:/path/cayenne-agent-3.0M3.jar=jpa-eager-load
This makes startup slower, but all the entity classes will be
guaranteed enhanced. This is missing from the docs, let me add it now.

Hi,
is it possible to declare mappings in a JPA conform orm.xml file
with Cayenne3M3. Unfortunately, I have not been successful so far.
