Subject Re: failing GOSSIP on localhost flooding the debug log
Date Fri, 02 Mar 2018 10:24:33 GMT
Whoops click "send" to fast

In SImpleSeedProvider :

String[] hosts = "10.1.20.10,10.1.21.10,10.1.22.10,".split(",", -1);
List<InetAddress> seeds = new ArrayList<InetAddress>(hosts.length);
for (String host : hosts)
{
System.out.println(InetAddress.getByName(host.trim()));
}

output :
/10.1.20.10
/10.1.21.10
/10.1.22.10
localhost/127.0.0.1

This might be consider a "bug" or a nice thing to fix by just ignoring
empty host don't you think ?

Have a nice day
