-----------------------------------------

I confirm that our environment is now stable in QA (Websphere / 10+ ear / load balancing) and no issue occurs anymore. No performance issues have been noticed either.

> There exists the possibility that the discriminator class cache in ValueMapDiscriminatorStrategy was originally created before the server fully loaded all classes. If this happens, the cache is incomplete and needs to be rebuilt. A simple enough strategy would be to just try rebuilding the cache, before giving up and throwing a CNFE, and check again.
