Cache L2 sharing objects with managed entities [message #1793834]

Hello guys,

Having the following structure:

Entity A -> includes an embedded component Address
L2 cache enabled, FULL type, the default one from EclipseLink

During a transaction, before commit time, if we modify the embedded component from a managed entity A, it is instantly reflected in the L2 cache.

We observed that behavior when debugging the L2 cache, more precise using the CacheImpl class (get object method). We observed that the managed entity object shares the same instance of embedded Address with the entity A object resulted from cache.

My question is, did someone else ever experienced this behavior? Does anyone have a solution for this?

Yes, it can be done if you have configured various optimizations, such as for reads to use objects directly from the shared cache. These optimizations are not meant for objects you are intending to change.

If this is not how you have hit the situation, more context on your setup would be needed.

Best Regards,
Chris
