Trying to make PEP work

I’m trying to publish a PEP item. I use Smack 4.2.2-SNAPSHOT, connecting to xmmp.jp that states support for PEP. My basic code is:

PEPManager pepManager = PEPManager.getInstanceFor(MyService.xmpp.connection);

boolean worked = pepManager.addPEPListener(new PEPListener() {
    @Override
    public void eventReceived(EntityBareJid from, EventElement event, Message message) {
        Toast.makeText(getApplicationContext(), "got pep event!", Toast.LENGTH_LONG).show();
    }

});

if (pepManager.isSupported())
    pepManager.publish(new Item("pepItem1"), "mysmacktest1@xmpp.jp");
else
    Toast.makeText(getApplicationContext(), "isSupported false", Toast.LENGTH_LONG).show();

And getting a PubSubException$NotAPubSubNodeException. Log:

Soo, what is wrong? What node should I be using? XEP-0163 states that “the root pubsub node simply is the account owner’s bare JID (localpart@domain.tld or < domain.tld >)”.
