> If slave replication mode is started on an encrypted database, derby fails 
> with a NPE and then hangs. The reason for the hang is that 
> LogToFile#initializeSlaveReplicationMode needs to scan the log to find the 
> end. For encrypted databases, this scan uses RawStoreFactory#decrypt. At this 
> stage, LTF#rawStoreFactory variable has not been set. 
> A solution may be to set this variable in LTF before scanning the log.
