SRV Type record

Hello,

I would like to update a SRV record with the following code:
            Name zone = Name.fromString("mydomain.com.");
           Name host = Name.fromString("host", zone);
            Update update = new Update(zone);
            update.replace(host, Type.SRV, 3600, "30443");

            Resolver res = new SimpleResolver();
            res.setTSIGKey(new TSIG("HMAC-MD5", "ddns-key",  "jlkdlfkjereuj" ));
            res.setTCP(true);

            Message response = res.send(update);


But, the following error occurs:
org.xbill.DNS.Tokenizer$TokenizerException: <none>:1: expected an integer
                at org.xbill.DNS.Tokenizer.exception(Tokenizer.java:691)
                at org.xbill.DNS.Tokenizer._getIdentifier(Tokenizer.java:383)

The replace() is ok with other type of record (A for instance), but not with SRV.

Any help, please ?

Stéphane
