[jboss-jira] [JBoss JIRA] Commented: (JBCACHE-830) Incorrect serialization of Collection and Map proxies

Brian Stansberry commented on JBCACHE-830:
------------------------------------------

In previous comment about not being sure about solution, I was thinking in terms of a non-PojoCacheable but serializable object that has a ref to a Collection/Map proxy.  If you place that in the cache, how do you ensure that on the recipient node, the object relationship to the cached Colleciton/Map is maintained?  But actually I don't think that's a requirement at all -- once you place a non-PojoCacheable object in the cache, any expectation of  maintaining object relationships on other nodes is gone.

So, I think the correct solution is to use writeReplace().

> The PojoCache Collection and Map proxies implement Serializable but don't do anything to override default serialization.  They have non-transient fields with refs to things like the cache itself, so serializing one of these is a big problem -- you serialize the whole cache.
> Not sure what the best solution to this is. Perhaps use writeReplace()?
