question about the useSetBytesForBlobs field

[B.J. Reed]

Hi, I've been looking at the DBDictionary class at a setBytes() issue 
and I have a question about the useSetBytesForBlobs field.  Seems that 
some Dictionaries set this to true and some leave it as the default of 
false.  The only thing this field does is determine if 
DBDictionary.setBytes() should use preparedStmt.setBytes() or use a 
ByteArrayInputStream to setBytes() regardless of whether the field is a 
small byte[] or a blob. 

The question is this...does anyone remember the history of this field? 
or why openJPA does setBytes() differently for different DB's?

Thanks,
