resultset.getObject() on BLOB type returns Blob by default in place of byte[]

resultset.getObject(val) on BLOB field type returns by default an Blob Object.

This is a regression, expected type is a byte[].

( this concerns only default return type for BLOB, getter with type indicated are ok :

• resultset.getBytes(val)
• resultset.getBlob(val)
• resultset.getObject(val, byte[].class)
• resultset.getObject(val, Blob.class)
  all returns expected type)
