When crlInfos can be null?
The value is fetched from. scmCertStore.getCrls(ImmutableList.of(crlId.get())); and this doesn't look like returning a null in any case. It is in general returning an empty list, if it can not find anything?
Secondly, If I understand the code correct, now if crlInfos is null, we will log the line below, so, will this crlInfos.get(0) not throw a NPE since crlInfos is null?
Thirdly, How this null check, preventing an IndexOutOfBoundsException

When crlInfos is empty, crlInfos.get(0) will have something feels unreasonable. After I communicated with @xiaoyuyao , it was because of the original negligence, it should be if (!crlInfos.isEmpty()).
