-----------------------------------------
[~alex_pl] IGNITE-13496 will fix this problem anyway, so I thought we can skip
a dedicated fix, that's why I linked it as "blocked by".
Please feel free to take this ticket if you'd like to do the fix.
> Thin client silently closes channel after inactivity
> ----------------------------------------------------

> Key: IGNITE-13719
> URL: https://issues.apache.org/jira/browse/IGNITE-13719
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.9
> Reporter: jifwin
> Assignee: Pavel Tupitsyn
> Priority: Major
>
> The following code works fine with ignite-core 2.8.0, but fails with 2.9.0
> (see the exception below). It looks like timeout is applied to client
> receiver thread. When it's not used for a while it gets closed silently.
> {code:java}
> public class IgniteDemo
> {
> public static final int TIMEOUT = 1000;
> public static void main(String[] args) throws InterruptedException
> {
> new IgniteDemo().run();
> }
> public void run() throws InterruptedException
> {
> final Ignite igniteServer = Ignition.start();
> final ClientConfiguration cfg = new
> ClientConfiguration().setAddresses("127.0.0.1:10800");
> cfg.setTimeout(TIMEOUT);
> final IgniteClient igniteClient = Ignition.startClient(cfg);
> final ClientCache<Object, Object> cache =
> igniteClient.getOrCreateCache("test");
> Thread.sleep(TIMEOUT);
> cache.put(1, 1);
> Thread.sleep(TIMEOUT);
> cache.put(2, 2);
