Tsz-wo Sze commented on RATIS-719:
----------------------------------
The group was removed by groupRemoveAsync so that the log was closed. After
that the LogAppender failed to read the log. It seems not a bug but the
message could be improved.
> SegmentedRaftLog#close fails with IllegalStateException
