Galder Zamarreno commented on HHH-5552:
---------------------------------------
I'm not sure whether it's needed or not. For the general case not at all cos the idea is that cache entries are deserialized when client thread requests it and such thread is generally the app thread that has the correct classloader. However, once I built a UT for it yday, I found out that the update timestamps keeps a local cache out of listener event key/values, so we might need your patch at least temporarily.

> While testing hibernate-infinispan, I see ClassNotFoundExceptions when the jgroups receiver thread attempts to deserialize an entity PK (in this case within the BaseRegion cache listener). Deserialization throw a CNFE since the custom key is not known to the context classloader of the jgroups up handler. It would appear that lazy deserialization is not sufficient to prevent this. Consequently, I think we need to reproduce the classloader handling from the jbosscache provider. That is, store a reference to the application classloader and swap thread context classloaders any time a key or an entity needs to be deserialized.
