[HARMONY-2723] [classlib][sql] RI returns positive value when SerialBlob.position (byte[] pattern, long start) can't find the pattern.

Description

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
