> 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
