Remote cache class cast exception

>From the logs of the Remote server I get class cast excepetions.

I have tried serializing the objects to disk, and these all seem to work. Is
there a simple way to generate the fully stack trace?

I log4j I thought the line below would generate a full stack trace, but
maybe this is different in Commons logging.

       catch ( IOException ioe )
        {
            log.error( "Failure getting from disk, cacheName: " + cacheName
+ ", key = " + key, ioe );
            reset();
        }


15:09:24,459 ERROR [IndexedDiskCache] Failure getting from disk, cacheName:
textCache, key = XXXYYY
java.lang.ClassCastException


Any hints appreciated.
