Problem description
===================
There is some problems with SerialClob class:

1. Useless constructor:
The spec. says:
Retrieves a stream to be used to write Ascii characters to the
CLOB value that this Clob object represents, starting at position pos.

  pos - the position at which to start writing to this CLOB object

return the stream to which ASCII encoded characters can be written

public java.io.OutputStream setAsciiStream(long pos) throws SerialException {
    //throw new UnsupportedOperationException();
    ByteArrayOutputStream baoStream = new ByteArrayOutputStream((int)pos);
    return (java.io.OutputStream)baoStream;
}

but there is no way to "write Ascii characters to the CLOB value" using
returned stream. Moreover JavaDoc for ByteArrayOutputStream says:

ByteArrayOutputStream(int size)
Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

So, ByteArrayOutputStream(int) parameter it is size but not a position.

Also it is good idea to tie internal CLOB buffer to the returned stream.

2. The same with next one:
    public java.io.Writer setCharacterStream(long pos) throws SerialException {
        // throw new UnsupportedOperationException();
        CharArrayWriter caWriter = new CharArrayWriter((int)pos);
        //caWriter.buf = buf;
        //caWriter.count = buf.length;
        
        return (java.io.Writer)caWriter;
    }

A lot of JCK tests failed due to these problems:
