Arun Kumar Jain commented on IGNITE-1026:
-----------------------------------------
Hey [~vkulichenko], In my case the call
{code:java}
IgniteQueue q = ignite.queue("queue", 0, null);
{code}
does not fail, but the object returned by it is null. In this case 'q' becomes
null. I get NPE in the next statement where I use 'q'.
This has been discussed in ignite forum
[here|http://apache-ignite-users.70518.x6.nabble.com/Use-IgniteQueue-in-client-td18133.html]
and Alexey has opened [this|https://issues.apache.org/jira/browse/IGNITE-6889]
issue to track.
