Stanislav Lukyanov commented on IGNITE-9825:
--------------------------------------------
Motivation for this is a regression recently introduced by
https://issues.apache.org/jira/browse/IGNITE-9326.
It was an NPE from a cache put that happens at the same time as a topology
change. Stack trace:

This regression is already fixed by the commit
https://github.com/apache/ignite/commit/6e0ff06, but with no tests.
The suggested test fails without the
https://github.com/apache/ignite/commit/6e0ff06 fix and passes with it.
> Need test for cache writes on unstable topology

> Need to add a simple test covering this.
