Vladislav Pyatkov updated IGNITE-19688:
---------------------------------------
Description:
org.apache.ignite.raft.jraft.core.ItNodeTest#testChangePeersStepsDownInJointConsensus
{noformat}
java.lang.NullPointerException
at
org.apache.ignite.raft.jraft.core.ItNodeTest.testChangePeersStepsDownInJointConsensus(ItNodeTest.java:3385)

at java.base/java.lang.reflect.Method.invoke(Method.java:566)
{noformat}
*Motivation*
The root cause of the issue is the method of getting leader
(_TestCluster#getLeader_) might return _null_ even if the test waits a leader
before (_TestCluster#waitLeader_).
*Implementation Notes*
Create a new method that returns a leader just after it has waited it
(_TestCluster#waitAndGetLeader_).
*Definition of Done*
Verify all places where method of waiting leader is used and replace it to new
one in that case where getting leader is not expected to receive _null_.
