Status 404 returned from restlet when doing PUT with If-None-Match set

[John Karp]

I'm getting a 404 error when attempting a PUT to a resource with the
If-None-Match request header set to '*'. I know a similar issue was
reported before and supposedly fixed, but I can reproduce this both
with 2.0.10 and 2.1rc1.

If I omit the If-None-Match header, the PUT works fine, returning 200.

I'm testing my app by executing these commands:
curl -v -X PUT -d 1 http://localhost:8182/a
curl -v -X PUT -d 2 --header 'If-None-Match: *' http://localhost:8182/b

which produces:

I'm not sure if attachments will work, so I have put the full source
code for TestCaseApp.java below:

                entries.put("foo", "bar");
        }

                TestCaseApp instance = new TestCaseApp();
                instance.run();
        }

        public void run() {
                try {

                        DataVaultRestlet restlet = new DataVaultRestlet();
                        getDefaultHost().attach(restlet);
                        start();

                        return router;

                                rep.append(name);
                        return rep.toString();

                        return entries.put(name, value);
                }
        }
}
