Agenda:
1. Enum tests: Michelle is just about ready to check in. Running last tests. In JPOX, enums are not persistent by default and seem to have trouble with numeric types. AI Michelle check in tests; AI Craig update spec to mandate enums as singleton, immutable objects and allow other enum support; AI Matthew propose a mapping of enum ordinal to database representation in metadata (this would make it easier to support legacy databases).
2. JDOHelper bootstrap issues: Matthew send around examples of bootstrapping. AI Craig update the spec. AI Craig continue discussion of configuration with serialization in mind. The issue is how to distinguish properties that are requested by the user versus properties that came out of a config file (either a .properties, a jdoconfig.xml, or persistence.xml) that might be different in the other vm where the persistence manager is being deserialized. This might affect the contract between JDOHelper and implementation PersistenceManagerFactory.
3. Serialization of PersistenceManager: The biggest issue is how to handle listeners. Other issue is how to handle classes that are not serializable. AI Craig write a proposal.
4. Other issuesJDOHelper has no compile time or runtime dependency on Persistence.class. This is a good thing. The general principle is that users should not require JPA in their environment if they are not using the JPA alignment features.
Subqueries: Should we add one more overloaded method addSubquery (Query outer, String resultExpression)? Probably not because we would need four more methods. AI Craig update JIRA. AI Michael check in the patch. This might cause JPOX to fail and all TCK tests to fail.
Email discussion: Proposed method to ask the persistence manager for managed instances might have a signature Object[ ] getManagedInstances (ObjectState[ ], Class... classes) which filters instances based on their state and class. This could be part of 2.1 or deferred to 2.2. Is this something that JPOX wants to see sooner?
