Hi Justin,
coming back to this discussion after while.

The PrevaylerImpl solution does not work. It needs a GenericSnapshotManager
- the NullSnapshotManager in my case, that combination in turn uses the
no-arg constructor from JavaSerializer. So I lived with the reflection code
stated above ... so far. But, it didn't feel right!
Now I'm using this VolatilePrevayler implementation, that is configurable
with a custom class loader and should catch some serialization problems. It
served me well so far, all tests are still green. A flaw-by-design is the
missing synchronization code, which if fine with my single threaded unit
tests. Should be easy to add, if it is needed some day. Do you (or somebody
else) see any major issue with this implementation? (I know, it does not
prevail ... ehm, persist anything).

Cheers,
Christian
