Looks like a good idea to me. I suppose you would keep backward compatibility?

From: "Adrian Crum" <adrian.c...@yahoo.com>
The blob field type is being used as a catch-all for multiple binary types. 
Right now getting an object from a blob field type
could return a byte array, a deserialized Java object, or a 
javax.sql.rowset.serial.SerialBlob object. There is no way to know for
sure what will be returned - the entity engine code tries various methods until 
one works.

I think it would be better to specify exactly what you intend to store in a 
BLOB SQL type: a byte array, a serialized Java object,
or some unknown binary type. So, I propose that we add two new field types: 
byte-array and object. Using Derby as an example, this
is what it would look like in fieldtypederby.xml:

<field-type-def type="blob" sql-type="BLOB" 
java-type="java.sql.Blob"></field-type-def>
<field-type-def type="byte-array" sql-type="BLOB" 
java-type="byte[]"></field-type-def>
<field-type-def type="object" sql-type="BLOB" 
java-type="java.lang.Object"></field-type-def>

Getting an object from each field type would return the respective Java object 
type.

What do you think?
