Detect invalid directives

Hello,

  I would like to handle invalid directives however they are just
passing through the templating engine as text, e.g. using the following
FTL "blah.ftl":

This is [#blah]content[/#blah].  This is [#fu] content.

and the code:

public class App {

    public static void main(String[] args) throws Exception {
        Configuration cfg = new Configuration();
        cfg.setTagSyntax(Configuration.SQUARE_BRACKET_TAG_SYNTAX);
       
        cfg.setDirectoryForTemplateLoading(new
File(System.getProperty("user.dir")));
       
        System.out.println("Compiling template: blah.ftl");
        FileReader reader = new
FileReader(System.getProperty("user.dir") + "/blah.ftl");
        // Expect ParseException
        Template template = new Template("blah.ftl", reader, cfg);

        System.out.println("Getting template from Configuration.");
        // Also expect ParseException
        template = cfg.getTemplate("blah.ftl");
        StringWriter writer = new StringWriter();
        template.process(new HashMap(), writer);
        System.out.println("Output: " + writer.toString());
    }
}

I get the output:

This is [#blah]content[/#blah].  This is [#fu] content.

In each Template reference, I'm expecting a compilation error w/
"Unknown directive" per the FMParser.jj grammar.  Any suggestions?

Thanks,

John T.
