Subject Re: [ApacheDS] Partition design and interfaces

Hi Pam,

I was thinking exactly along the same lines here especiaally since JE's
DatabaseException does not extend IOException.  BTW this is funny but note
that I already refactored from NamingException to IOException but just now
felt I was doing something stupid.

Thanks for your comments,
Alex
