Duong commented on RATIS-2104:
------------------------------
Tried that, same result [~szetszwo]. The finally block is skipped sometimes
when MiniRaftCluster is down. I think it's related to the fact that the grpc
executor threads are daemon.
> TestLeaderInstallSnapshot may fail with java.lang.IllegalStateException:
> allLeaks.size = 4
