Problem description
===================
There is following problems with SerialBlob class:

1. Following method throws an exception if start==0:
The spec. says:
* Returns the position in this <code>SerialBlob</code> object where
* the given pattern of bytes begins, starting the search at the
* specified position.
...
* @param start the position of the byte in this
* <code>SerialBlob</code> object from which to begin
* the search; the first position is <code>0?1</code>;
* must not be less than <code>0</code> nor greater than
* the length of this <code>SerialBlob</code> object

we can pass 'start' == 0 because it is not less than 0 but in this case
method will throw an exception.

    public long position(byte[] pattern, long start) throws SerialException {
        int pos = (int)(start - 1);
// SSW: pos is -1 here if start = 0
        long beginpos;
        int i = 0;
        long patlen = pattern.length;

        if (start < 0 || start > len) {
            return -1;
        }
           
        while (pos < len) {
            i = 0;
            beginpos = pos + 1;
            while (pattern[i++] == buf[pos++]) {
// SSW: buf[-1] throws ArrayIndexOutOfBoundsException
                if (i == patlen) {
                    return beginpos;
                }
            }
        }
        return -1;
    }

2. The same with next one:
    public long position(Blob pattern, long start)

because it is just a wrapper for public long position(byte[] pattern, long start)

3. public java.io.OutputStream setBinaryStream(long pos)

It is looks just like factory method to get an OutputStream
