Description

Hi, as discussed in dev mailing list, SerialBlob.truncate(long length) should not change buffer length is the length parameter is invalid. Following test shows the case:
public void testTruncateJ() throws Exception {
byte[] buf =

{ 1, 2, 3, 4, 5, 6, 7, 8 }

;
SerialBlob serialBlob1 = new SerialBlob(buf);
try

{ serialBlob1.truncate(-1); }

catch (SerialException e)

{ System.out.println(e.getMessage()); }

System.out.println(serialBlob1.length());
}
RI output is as follow:
Invalid arguments: position cannot be less that 1
-1
The buffer length is changed to -1 while SerialException is thrown too. Keeping the length as the old value makes more sense. Harmony won't follow RI's behaviour for this case, and keep it as a non-different-bug from RI.

Best regards,
Andrew
