Tsz Wo Nicholas Sze commented on RATIS-506:
-------------------------------------------
[~arpitagarwal], thanks for reviewing the patch.
The state machine can lag behind. The assertion is to wait for the state
machine to catch up.
lastCommittedEntry actually is the entry at loggedCommitIndex. There could be
newly added entries so that it is possible to have
lastCommittedEntry.getIndex() < lastAppliedTermIndex.getIndex().
> ServerRestartTests.testRestartCommitIndex may fail intermittently
