Apache sshd prints out a stacktrace with above mentioned excpetion, but application seems still running normal.

This occurs in different constellations using JGit.

One big problem with this is, that for example searching logs for 'exception' will always be true. So we have to filter it out as far as possible.
That makes every configuration for build tools very complicated.
Or every search by hand one has to filter these messages out.

My current version of JGit is 6.6.0.

The simpliest code to reproduce is:

    System.setProperty("sun.security.jgss.native", "true");
    final Collection<Ref> c = Git.lsRemoteRepository() //
      .setRemote(REPO) //
      .call();
    System.out.printf("%s: %d%n", REPO, Integer.valueOf(c.size()));


Which then gives me following output:

ssh://hostname/repopathandname.git: Exception in thread "Thread-3" java.lang.IllegalStateException: Executor has been shut down
	at org.apache.sshd.common.util.ValidateUtils.createFormattedException(ValidateUtils.java:213)

One strange behaviour I found:

Having a breakpoint in the constructor of org.apache.sshd.client.SshClient.SshClient and running that code in debug-mode in Eclipse does not reproduce the exception.
Running normally does.
