Subject Re: Ignite 2.7.0 : server node: null pointer exception
Date Wed, 24 Jul 2019 23:29:49 GMT
Igor, thanks for looking into this.

Even if the root cause is on an application end, our code mustn't generate
an NPE.

Ignite dev community and *Ivan Rakov* in particular, have you seen this
before? Should we file a ticket or the issue has already been resolved?
