             Summary: Doing RaftServer.close() hangs up the process
                 Key: RATIS-1329
                 URL: https://issues.apache.org/jira/browse/RATIS-1329
             Project: Ratis
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Mario Georgiev
         Attachments: ratis-grpc-hangup-on-close-grpc-jstack.txt, 
ratis-grpc-hangup-on-close.zip, ratis-netty-hangup-on-close-netty-jstack.txt, 
ratis-netty-hangup-on-close.zip

Build the jar with 
```
./gradlew uber
navigate to the build/libs/ and run the uber jar.
```
Initially thought it only happens on Netty, but switched to GRPC and same thing.

Issue is both on Netty && GRPC, you might have to run the jar a few times to 
get the hang up. (attached jstack for both of the reproducible test cases)

Am i doing something incorrect in the code, or its just a bug.
