Ilya Kasnacheev commented on IGNITE-8343:
-----------------------------------------
IMO InetSocketAddress.getAddress() should always be null-checked, via
IgniteUtils method for example.
> InetSocketAddress.getAddress() returns null, should check it in
> TcpCommunicationSpi

> Key: IGNITE-8343
> URL: https://issues.apache.org/jira/browse/IGNITE-8343
> Project: Ignite
> Issue Type: Bug
> Components: general
> Reporter: Ilya Kasnacheev
> Assignee: Ilya Kasnacheev
> Priority: Major
>
> This is especially notorious in the following scenario:
> {code}
> // -Djava.net.preferIPv4Stack=true
> System.err.println(new InetSocketAddress("0:0:0:0:0:0:0:1%lo",
> 12345).getAddress()); // null
> {code}
> Yes we already warn if different nodes have differing preferIPv4Stack, still
> this is warning not a error, and there may be other cases where getAddress()
> returns null. Should make a check.
