Serialization in existing ECF providers [message #631040]

We're currently looking at different scenarios in which ECF could be running in our environment. One scenario that seems pretty likely is that different class levels could exist in separate JVM's. Does the current set of ECF providers offer support for this? Or would we have to guarantee that all classes are at the same level across JVM's?
We're specifically using the R-OSGi provider and were wondering what type of serialization is used - is it the standard Java serialization? In general, where can I find more information on what type of serialization is used for existing providers?

Thanks!

Hi,

r-OSGi comes with a feature named Smart Serialization. Unfortunately I
could not find documentation (you might be able to find something in the
papers about r-OSGi though [0]) so you will have to study the source.
ch.ethz.iks.util.SmartObjectOutputStream is probably a good starting ground.
