BLOB operations in user defined prepared statements are not consistent with operations on entities

[leitaop]

When setting a prepared statement column the following is generally used:
if (o instanceof byte[])
{ ps.ps.setBytes(i, (byte[]) o); }
else
{ ps.ps.setObject(i, o); }
whereas when using entities, values of BLOB columns are always serialized (custom encoded starting in PDB 2.0.5). Therefore, if a BLOB value is updated using an user-defined prepared statement, the written value will not be the returned on subsequent reads. For example, if a byte[] containing a serialized value is written, the read value will not be the provided byte[], it will be the de-serialized object.
