Ivan Pavlukhin commented on IGNITE-12976:
-----------------------------------------

[~Kostyuckovich], the fix itself looks good. But there is a couple of moments 
specific to Ignite development process which should be addressed:
# Each test class should be added to a test suite to run in CI. Here you can 
use 
https://github.com/apache/ignite/blob/master/modules/spring-data/src/test/java/org/apache/ignite/testsuites/IgniteSpringDataTestSuite.java
 (and counterparts for different spring-data versions).
# Usually patches should be checked with TC bot (https://mtcga.gridgain.com/), 
check an 
[instruction|https://cwiki.apache.org/confluence/display/IGNITE/Apache+Ignite+Teamcity+Bot#ApacheIgniteTeamcityBot-HowtocheckaPRwiththeTCBot].
 Do not hesitate to ask if something is not clear.
