Netbeans not keeping added server after restart

When I add a new server (glassfish) or another, it works just fine. I can startup the server and deploy apps on it.

But, every 开发者_Go百科time I restart netbeans the added servers are not there. It means I must add servers every time I open netbeans.

I'm using netbeans7.

Thanks.

Well, it is not happening any more on netbeans 7.2. If it was a bug, it has been fixed.
