Kristian Waagan resolved DERBY-4102.
------------------------------------

       Resolution: Fixed
    Fix Version/s: 10.5.3.1
                   10.4.2.1

The regression tests ran cleanly on both the 10.5 and 10.4 branch.
Merged fix into the 10.5 and 10.4 branches with revisions 903222 and 903223.

This should complete the work on this issue.

> 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.
