[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
