e.g: ``` Assertions.assertTrue(false); => Assertions.fail(); ``` ``` Assertions.assertTrue(future instanceof AppendFuture); => Assertions.assertInstanceOf(AppendFuture.class, future); ```

Delete the synchronized by use the cas update.

This is the original code ```java synchronized (knownMaxTermInGroup) { switch (x.getVoteResult()) { case ACCEPT: acceptedNum.incrementAndGet(); break; case REJECT_ALREADY_HAS_LEADER: alreadyHasLeader.compareAndSet(false, true); break; case REJECT_TERM_SMALL_THAN_LEDGER: case REJECT_EXPIRED_VOTE_TERM: if (x.getTerm() > knownMaxTermInGroup.get()) {...

有一些语句的描述，可以调整一下，阅读能更加流畅一些。
