Re: [eclipselink-dev] VM Managed EM feature (214661)

Thanks for the feedback Mike,
1. No, it would be very difficult to switch this dynamically.  Perhaps a future consideration.
2. ok, makes sense - done
3. only for FORCED_WEAK. and I have updated the java doc with a note saying changes could be lost
4. Perhaps but even with the link they will not know they are using it (weaving) but it is mentioned in WEAK so I will add link.

Nice feature.

- Is there a dynamic API to set this option on an EM? This would be nice for those extended PC EMs that one gets from SFSB...

- I would name the property: eclipselink.persistence-context.reference-mode

- If an object is not change-tracked then isn’t there the possibility that it will be gc’ed and the change discarded? If this is indeed the case then we need a better warning on the FORCE_WEAK option explaining this, since this could be unexpected and bad.

- It would be nice to have a reference to change tracking javadoc, since a user of this option may not be completely aware/familiar with whether or not they are using change tracking and which option to use, etc.
