    Description

      The code below results in an assert error (with sane jars) or a ClassCastException (with insane jars):

      PreparedStatement ps = c.prepareStatement("values cast(? as blob)");
      int len = 32 * 1024;
      ps.setBinaryStream(1, new ByteArrayInputStream(new byte[len]), len);
      ResultSet rs = ps.executeQuery();
      while (rs.next())

      { rs.getBlob(1); }

      If len < 32K there is no error.
