[classlib][sql] RI returns positive value when SerialBlob.position (byte[] pattern, long start) can't find the pattern.
-----------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2723
                 URL: http://issues.apache.org/jira/browse/HARMONY-2723
             Project: Harmony
          Issue Type: Bug
          Components: Non-bug differences from RI
            Reporter: Andrew Zhang


RI's behaviour of SerialBlob.postion(byte[] pattern, long start) looks strange. Consider following code:
    private void testPosition_BytePattern()
            throws SerialException, SQLException {

        byte[] buf = { 1, 2, 3, 4, 5, 6, 7, 8 };
        SerialBlob blob = new SerialBlob(buf);


        byte[]  pattern = new byte[] { 2, 4 };
        long pos = blob.position(pattern, 1);
        System.out.println("pos = " + pos);
        // FIXME: RI's bug?
        assertEquals(-1, pos);

    }

RI's output: 
pos = 3
Harmony's output:
pos = -1

As discussed in the mailing list, we'd regard it as a bug of RI.  And the implementation of Harmony looks reasonable. Thanks!

Best regards,
Andrew
