  Specification excerpt:
  ======================
  
  --------- J2SE API spec v.1.5 ---------
  ...
  public SerialClob(Clob clob)
             throws SerialException,
                    SQLException

  Constructs a SerialClob object that is a serialized version of the given Clob
object.

  The new SerialClob object is initialized with the data from the Clob object;
therefore,
  the Clob object should have previously brought the SQL CLOB value's data over
to the client
  from the database. Otherwise, the new SerialClob object object will contain no
data.

  Note: The Clob object supplied to this constructor cannot return null for
  the Clob.getCharacterStream() and Clob.getAsciiStream methods. This SerialClob
constructor
  cannot serialize a Clob object in this instance and will throw an SQLException
object.

  Parameters:
  clob - the Clob object from which this SerialClob object is to be constructed;
cannot be null
  Throws:
  SerialException - if an error occurs during serialization
  SQLException - if a SQL error occurs in capturing the CLOB; if the Clob object
is a null; or
  if both the Clob.getCharacterStream() and Clob.getAsciiStream() methods on the
Clob return a null
  ...
  ---------- end-of-excerpt ---------------


  Problem description
  ===================
  After fix of 5063284 the designated constructor throws java.sql.SQLException
if ONE
  of clob.getCharacterStream() and clob.getAsciiStream() returns null.
  But the spec says that SQLException should be thrown
  "if both the Clob.getCharacterStream() and Clob.getAsciiStream() methods on
the Clob return a null".
