           Summary: BeanUtils.copyProperties changes nulls (byte arrays) to
                    empty byte arrays
           Product: Commons
           Version: 1.6 Final
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Bean Utilities
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: szczepiq@gmail.com


BeanUtils.copyProperties changes nulls (byte arrays) to empty byte arrays. 
If an object has byte array field (and necessary accessors), that is null for
instance, the copy destination object will have empty byte array ( byte[0] ).

I noticed that ByteArrayConverter does not work well - if a convert(type, value)
method gets value == null, returns byte[0].

That's why copyProperties does not work properly - I expect null to be copied to
oher project, not an empty array.

I went through this problem by creating my own converter, but please consider if
API contract of method copyProperties() is fulfilled well.

Thank you,
Regards,
