Amelchev Nikita commented on IGNITE-9948:
-----------------------------------------
The test was failed by infrastructure problems (too long persistence checkpoint
and closing session by timeout). Now the test doesn't fall anymore ([test
history|https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=-4416495803371140089&tab=testDetails&branch_IgniteTests24Java8=%3Cdefault%3E]).
I suggest adding the additional check for command result checking. It looks
better then NPE and will clarify a reason if something goes wrong.
[~dpavlov], could you help with issue resolving?

> The possible reason is the race between getting cache instance on different
> nodes:
> # Jetty query create cache successfully on one node.
> # PME doesn't have completed.
> # The test fails with NPE while getting the instance of cache on another node.
