> This new bug is really serious and tricky. It has eluded us but comes out now 
> thanks to a crazy size effect it has on Windows.  
> First a characterization of the bug.  An entry (Attributes object) may be 
> valid and still contain an Attribute which has both byte[] and String array 
> values.  Some may suggest that this is invalid since attributes are, 
> according to their syntax, either binary of human readable.  However this is 
> not the case.  The fact that an attributeType is human readable has no 
> bearing on how the user supplies the value.  Human readable data can be 
> provided as binary information so long as it still conforms to the syntax of 
> the attribute.
> Here's an example entry which would cause such a failure:
>     dn: cn=person1,ou=system
>     objectClass: organizationalPerson
>     cn: person1
>     sn: sn_person1
>     seealso: cn=Good One,ou=people,o=sevenSeas
>     seealso:: Y249QmFkIEXDqWvDoCxvdT1wZW9wbGUsbz1zZXZlblNlYXM=
> This entry will cause the AttributeSerializerUtils.serialize() method to blow 
> a ClassCastException.  Note the log of the error can be found attached to 
> this issue.
