MessageFormat fails to perform the proper substitution.
The test program contains 2 similar examples. The first example is a skeletal
version of the second. The first one performs the substitution, the second one
ignores it.but it should not ignore it.

public class Test {

    private static MessageFormat TEST1 = new MessageFormat(
        "<>" +
            tr(td("?") +
               td("<>")) +
            tr(td("?") +
               td("<>")) +
            tr(td("?") +
               td("<>")) +
            tr(td("") + td("{0}")) +
        "</>" +
        "<=\"\">" +
        "<p>" +
        "{1}" +
        "<=\"\">");

    private static MessageFormat TEST2 = new MessageFormat(
        "<table>" +
            tr(td("Offer cancellation and rescheduling?") +
               td("<input type=checkbox>")) +
            tr(td("Use the customer's name?") +
               td("<input type=checkbox>")) +
            tr(td("Include a callback number?") +
               td("<input type=checkbox>")) +
            tr(td("Callback number") + td("{0}")) +
        "</table>" +
        "<input type=submit value=\"save changes\">" +
        "<p>" +
        "Test these settings by calling {1} <br> " +
        "<input type=submit value=\"call now\">");

    private static FieldPosition IGNORE = new FieldPosition(0);

    public static void main(String[] ignored)
        throws Exception
    {
        StringBuffer out = new StringBuffer();
        Object[] args = new Object[] {"phone #1" , "phone#2"};
        TEST1.format(args,out,IGNORE);
        TEST2.format(args,out,IGNORE);
        System.out.println(out.toString());
    }

    private static String tr(String s) {
        return "<tr>" + s + "</tr>";
    }

    private static String td(String s) {
        return "<td>" + s + "</td>";
    }
}

Output looks like:

<><tr><td>?</td><td><></td></tr><tr><td>?</td><td><></td></tr><tr><td>?</td><td>
<></td></tr><tr><td></td><td>phone #1</td></tr></><=""><p>phone#2<=""><table><tr
><td>Offer cancellation and rescheduling?</td><td><input type=checkbox></td></tr
><tr><td>Use the customers name?</td><td><input type=checkbox></td></tr><tr><td>
Include a callback number?</td><td><input type=checkbox></td></tr><tr><td>Callba
ck number</td><td>{0}</td></tr></table><input type=submit value="save changes"><
p>Test these settings by calling {1} <br> <input type=submit value="call now">

The thing to note is that {0} and {1} don't get substituted for in example #2.
