I'm having a class loading problem with an ehcache persisted cache and dm server (1.0.1.RELEASE). I keep getting a ClassNotFoundException when my server is restarted--specifically when a bundle attempts to load the cache's index. Here is the scenario: I have a serializable class, AKey, in a domain bundle; in a separate bundle I have a persistent ehcache instance. I can add/retrieve items no problem and flush to disk, but when the server is restarted, I get ClassNotFoundException: AKey. Any ideas to get around this? I'd really like to be able to use AKey as a key.
