Subject [jira] [Created] (DERBY-5489) getBinary() returns incorrect data after getObject() call on BLOB column

getBinary() returns incorrect data after getObject() call on BLOB column
------------------------------------------------------------------------

                 Key: DERBY-5489
                 URL: https://issues.apache.org/jira/browse/DERBY-5489
             Project: Derby
          Issue Type: Bug
    Affects Versions: 10.8.2.2, 10.7.1.1
            Reporter: Pawel Fronczak


When ResultSet.getObject(int) is called on a BLOB column, the correct EmbedBlob object is
returned. But if afterwards the ResultSet.getBytes(int) is called on the same row, the returned
array contains invalid data - it is offset by 3 bytes and its size is incorrect.
The problem only occurs when the stored BLOB is large enough to be internally represented
by stream and not by array of bytes (at least ~32KiB).
It seems that the getObject method shifts the stream position and therefore the getBytes method
starts to read the data after the third byte, thus incorrectly calculating its length.
